Origin: The Persian Plateau and the highlands of Central Asia, where the wild ancestor <em>Spinacia tetrandra</em> grows in stony, semi-arid terrain; the cultivated form was domesticated within this same region, most likely in the Sassanid Persian heartland of present-day Iran
A clarification that echoes the one made for tea in this atlas: just as 'tea' here denotes Camellia sinensis and not the many other plants steeped in hot water under that borrowed name, 'spinach' here means Spinacia oleracea and nothing else. This matters because a persistent confusion runs through the popular and even the scholarly literature: ancient Greek and Roman food writing is regularly cited as evidence for spinach in the classical world, yet the relevant texts describe no such plant. The Greek collective term horta (χόρτα) denotes any edible green gathered from field or hillside: orache (Atriplex hortensis), mallow (Malva species), blite (Chenopodium species), ground elder (Aegopodium podagraria), nettles, sorrel, and dozens of others, none of which are Spinacia oleracea. The Romans had similarly many olera (potherbs) but no spinach among them; the word 'Spinacia' does not appear in any classical Latin source because the plant had not arrived. The earliest unambiguous references to cultivated true spinach in Mediterranean or European writing date to Arab agricultural texts of the 9th century CE, by which time the plant had been in Arab cultivation for some generations and in Persian cultivation for considerably longer. This entry covers Spinacia oleracea from its domestication in Persia to its global diffusion; other plants sometimes called 'spinach' in English, among them Malabar spinach (Basella alba), New Zealand spinach (Tetragonia tetragonioides), and water spinach or kangkong (Ipomoea aquatica), are unrelated species from different plant families, and they appear in this atlas only when they arise naturally in the cooking traditions of other ingredients.
Spinacia oleracea is an annual or biennial herb of the goosefoot family, Amaranthaceae, whose wild ancestor Spinacia tetrandra is native to the rocky, semi-arid slopes and steppe margins of the Iranian Plateau and the adjacent highlands stretching through Afghanistan and into Central Asia. The cultivated form was domesticated from this wild progenitor within that same region; the precise moment is impossible to recover, since the relevant Persian records are sparse and the earliest explicit descriptions of the plant arrive already filtered through Arab and Chinese sources. The Chinese Tang Dynasty text Shiyi Bencao (食疗本草, dietary supplement text, c. 7th century CE) records that spinach was brought to China as a diplomatic gift from the land of 'Boluo' (understood by later scholars to mean Nepal, or the broader northwest Indian sphere) during the reign of Emperor Taizong (r. 626–649 CE), implying that the plant was already being cultivated somewhere between Persia and the Indian subcontinent by at least the early 7th century CE, and in Persia itself probably well before that.
Spinacia oleracea is unusual among major leaf vegetables in having separate male and female plants (it is dioecious), and the seeds of some varieties bear prominent spines, a feature that may have given the plant its name in the European linguistic chain that derived ultimately from Persian. The plant is a cool-season annual that thrives in the temperature range of 10–20°C and bolts to flower rapidly in the heat of summer, a trait that continues to define where it is grown seasonally and commercially. Its leaves are rich in iron, folate, and vitamins A, C, and K, as well as in oxalic acid, which binds to some minerals and reduces their bioavailability; the popular belief, partly traceable to a misprint in a 19th-century German study, that spinach has an exceptionally high iron content beyond other leafy vegetables is now understood to be an error.
Cultivar groups within Spinacia oleracea include the savoy types (heavily crinkled, textured leaves, preferred in northern Europe and the United States for fresh market), the smooth or flat-leaf types (larger, easier to wash and process, preferred for canning, freezing, and the baby-leaf market), and the semi-savoy types (a compromise between the two). These cultivar groups have no separate geographic origins; they represent divergence through centuries of selection within a single domesticated species, and they do not warrant separate journey points on the spinach atlas.
The journey of spinach from its Persian origin to its position as one of the most widely grown leafy vegetables on earth took approximately fourteen centuries and followed three independent vectors: the Arab expansion westward through North Africa and into Iberia and Sicily; the Silk Road eastward to Tang Dynasty China and from there to Japan; and the Persian overland routes southward into the Indian subcontinent. These three arms of the spinach's diffusion produced the three great culinary traditions of the plant: the Persian-Indian tradition of long-cooked spinach in dairy and spiced sauces; the Arab-Mediterranean tradition of spinach with chickpeas and dried fruits; and the East Asian tradition of briefly cooked spinach dressed with sesame and soy, each one distinctive enough that a cook from one tradition would barely recognise the plant's role in the other two.
The Arab vector was the most consequential for European food history. Arab agricultural scientists of the Abbasid Caliphate (750–1258 CE) described spinach as 'isfanāj' (إسفناج), clearly identifying it as a Persian plant that the Arabs had adopted into their own kitchens and carried westward with their expansion across North Africa. The agricultural texts of al-Andalus, principally Ibn al-Awwam's Kitāb al-Filāḥa (Book of Agriculture, 12th century Seville), describe its cultivation in the gardens of Islamic Iberia; from there it entered the Norman court of Sicily, where Arab gardeners continued to cultivate the plants they had grown under the preceding Sicilian emirate, and from Sicily it spread northward into the Christian kitchens of medieval Europe. The Crusaders returned from the Levant with spinach seeds as well, and the conjunction of these two channels (Mediterranean/Sicilian diffusion and Crusader return) meant that spinach was known in French, English, and German cooking by the mid-14th century, appearing in the English recipe collection known as The Forme of Cury (c. 1390) as 'spynoches' and in German records of similar date.
The Renaissance court of Florence developed a particular association with spinach, codified in the culinary term 'à la Florentine' that the French kitchen applied to any dish incorporating creamed spinach. The precise role of Catherine de Medici, who married the future Henry II of France in 1533, in introducing this association is much debated; the story that she brought Florentine cooks and Florentine spinach preferences to the French court is probably considerably embellished. What is clear is that northern Italian Renaissance cooking had genuinely elevated spinach as a refined ingredient by the mid-16th century, and that the 'à la Florentine' designation in French cuisine reflects a real cultural transfer, whatever the degree to which it was specifically Catherine de Medici's doing.
The Ottoman kitchen absorbed spinach from the Arab culinary world of Anatolia, where the plant had been cultivated since the Arab expansion of the 7th and 8th centuries CE. The Ottoman börek tradition developed the spinach and cheese filling as one of its most important forms; the Greek spanakopita, the defining spinach dish of the modern Aegean world, descends from this Ottoman börek tradition rather than from any ancient Greek use of the plant, because ancient Greece, as noted above, had no Spinacia oleracea. It arrived in Greece through the Ottoman cultural sphere, and the filo pastry technique itself is an Ottoman inheritance.
The East Asian journey began in 647 CE when King Narendradeva of Nepal sent spinach as a diplomatic gift to the Tang Emperor Taizong at Chang'an. From China's Silk Road capital the plant spread gradually through Chinese agriculture, becoming the 菠菜 (bōcài) of Chinese kitchens, and reached Japan during the Edo period (first cultivated there around 1688) where it became the ほうれん草 (hōrensō) of the Japanese table. Both the Chinese and Japanese traditions favour briefly cooked spinach dressed lightly with garlic, sesame, soy, and dashi, in striking contrast to the long-cooked, heavily spiced Indian and Persian traditions.
In India, the spinach plant and the word 'palak' (पालक) (an independent Sanskrit-derived name with no etymological relationship to the Persian 'esfanāj') suggest a long-established cultivation tradition, though the precise date of introduction from Persia or Central Asia is unknown. What is certain is that by the Mughal period spinach had become deeply embedded in the northern Indian kitchen, particularly in the creamy leaf preparations such as palak paneer that would eventually become the most internationally recognised Indian vegetable dish.
European colonial settlement carried spinach to the Americas from the 16th century onward; Martha Washington's cookbook contains spinach recipes, and the American creamed spinach that became a steakhouse staple reflects the French-influenced cooking of the eastern seaboard. The cultural moment that more than any other defined spinach's place in the modern American imagination came in 1929, when the cartoonist E. C. Segar gave his character Popeye an inexhaustible appetite for tinned spinach; the subsequent decades saw spinach consumption in the United States rise markedly. Today the Salinas Valley of California is among the world's foremost spinach-producing regions, and the commercial baby spinach market (smooth-leaf varieties harvested young, washed, and sold ready to eat) is a product of late-20th-century food processing and refrigerated logistics that has made the leaf a global salad standard.
Spinach is among the most widely cultivated leafy vegetables on earth, grown commercially on every inhabited continent and consumed in culinary traditions ranging from the Persian plateau to the Japanese archipelago. China is the world's overwhelmingly largest producer, accounting for more than ninety per cent of global output, followed at a considerable distance by the United States, Turkey, and Japan. In China the plant is eaten stir-fried with garlic, dissolved into congee, and added to dumplings; in Japan it is blanched and dressed with dashi or sesame paste in the ohitashi and goma-ae preparations that are among the most refined expressions of the vegetable in any cuisine; in South and Southeast Asia the related 'palak' tradition of long-cooked spinach in cream, yogurt, or lentil-based sauces produces some of the most complex preparations of the leaf.
In the Mediterranean world spinach remains important in both the Arab inheritance (espinacas con garbanzos in Seville, the spinach-filled börek of Turkey and the Levant) and the Greek tradition (spanakopita, spanakorizo). Italy maintains the spinach-ricotta partnership in pasta fillings and tarts that has been characteristic of the Italian kitchen since the medieval period. France upholds the 'à la Florentine' standard in its restaurant and home-cooking tradition, and creamed spinach has become the default accompaniment to beef in American steakhouses.
Nutritionally, spinach is valued for its folate, vitamin K, vitamin A, and antioxidant content, including lutein and zeaxanthin, which are associated with eye health. The widely circulated claim that spinach has exceptional iron content rests on a misprint in a 19th-century German study that placed the decimal point one position too far to the right; cooked spinach does contain useful iron but not the extraordinary quantity that Popeye and popular culture have attached to it. The oxalic acid in raw spinach also forms insoluble calcium oxalate, slightly reducing calcium absorption, a reason why briefly cooking or wilting spinach is nutritionally as well as culinarily sensible.
Two large absences on this map are worth stating plainly rather than filling in. Sub-Saharan Africa grows very little Spinacia oleracea, and most of what is sold and cooked there as spinach is something else: amaranth (Amaranthus species), called morogo in southern Africa and efo in Yorubaland, or Swiss chard, which South African greengrocers label spinach outright. Those are good greens with their own traditions and they are not this plant. Russia and the Slavic north likewise never took to it: the cold-climate leaf crops there are cabbage and sorrel, and the sour green soups of the region are built on sorrel rather than spinach. Georgia, on the southern side of the Caucasus, is as far into that sphere as spinach genuinely reached.
Historical Journey of Spinach
The Iranian Plateau & Sassanid Persia — c. 300 CE
True spinach (Spinacia oleracea) was domesticated in the Persian heartland from its wild ancestor Spinacia tetrandra, a plant native to the stony, calcium-rich soils of the Iranian Plateau and the semi-arid hillsides stretching eastward into Afghanistan and Central Asia. The earliest direct evidence for cultivation under the Sassanid Empire (224–651 CE) is indirect rather than textual, inferred from the Arabic agricultural literature of the centuries immediately following the Arab conquest of Persia: when 9th-century Abbasid agronomists wrote about 'isfanāj', they described it as a Persian plant that the Arabs had received and adopted, pointing backward to cultivation that must have preceded the Islamic conquests by some generations. The Persian language gave spinach to every European tongue ('aspanāj' in Persian, 'isfānāj' in Arabic, 'espinaca' in Spanish, 'spinach' in English) a linguistic trail that is among the clearest in food etymology and that marks the Iranian Plateau as unmistakably the plant's cultural homeland regardless of the scarcity of contemporary Sassanid documentation.
The Persian kitchen developed preparations for spinach that became the foundations of the entire eastern culinary tradition of the plant: long braising in aromatic oil or fat until the leaf completely wilts and surrenders its moisture; the combination with dried fruit (particularly alu, the dried sour plum) for a sweet-sour note; and the integration with dairy, particularly the strained yogurt kashk and the fresh curd cheese of the palace kitchen. These techniques characterise the khoresh-e esfenaj (spinach stew with lamb and prunes) and the borani-e esfenaj (spinach beaten into yogurt with garlic and walnut) that are among the most ancient continuous preparations of the plant.
The Gangetic Plain and Northern India — c. 600 CE
Spinach reached the Indian subcontinent from the Persian-Central Asian heartland, most probably through the overland trade routes that connected the Iranian Plateau to the Indus Valley and the Gangetic Plain across the passes of the Hindu Kush and through the ancient cities of Kandahar and Taxila. The Sanskrit-derived word 'pālak' (पालक), used for spinach in Hindi, Urdu, and several other Indian languages, is an independent coinage with no etymological connection to the Persian 'isfanāj', which suggests that the plant's adoption in India was direct from the cultivation region rather than through the Arab linguistic intermediary that later carried it to Europe. Whether spinach entered India before or after the Arab conquests of Persia (7th century CE) is uncertain; the Tang Dynasty Chinese record of 647 CE, which describes spinach arriving in China as a gift from Nepal, implies that the plant was already being grown in the northwest Indian sphere by that date.
In the Indian kitchen, spinach was treated with a fundamental difference of approach from the Persian: where Persian cooking dissolved spinach into the braising liquid of a khoresh, the Indian tradition retained the leaf as an identifiable element in spiced preparations, combining it with paneer (fresh pressed cheese), lentils, potatoes, and other vegetables in the saag and palak dishes that became the staple expressions of the plant in the northern subcontinent. Palak paneer (spinach cooked with onion, garlic, ginger, and spices until the leaves are completely soft, then finished with cubes of fried paneer in a cream-enriched sauce) is today among the most internationally recognised Indian vegetable dishes, and saag aloo, the potato-and-spinach curry of the north, is one of the most common household preparations across Punjab, Uttar Pradesh, and the wider Hindi-speaking belt.
Tang Dynasty Chang'an and the Silk Road Heartland, China — c. 647 CE
The earliest precisely dated record of spinach in China appears in the historical annals of the Tang Dynasty: in 647 CE, King Narendradeva of Nepal sent spinach seeds (along with lettuce and other plants) as a diplomatic gift to Emperor Taizong at the imperial capital of Chang'an (modern Xi'an), the eastern terminus of the Silk Road. The Tang court's encyclopaedic record-keeping preserved this detail, and several subsequent 8th-century Chinese botanical and dietary texts (including the Bencao Shiyi of Chen Cangqi, c. 739 CE) describe the plant as having come from the land of 'Boluo', understood as Nepal or the broader northwest Indian sphere, the same geographic context that the Persian and Central Asian origin would produce if followed along the Silk Road.
The Chinese gave the plant the name 菠菜 (bōcài, meaning approximately 'ba-vegetable' or 'Boluo vegetable'), coining a new character specifically for it. The plant spread through Tang and subsequent Song, Ming, and Qing period cultivation, becoming a staple of the northern Chinese vegetable garden and appearing throughout the Chinese kitchen in stir-fries, soups, dumplings, and noodle dishes. The Chinese approach to spinach emphasises speed: a very brief high-heat encounter with a wok and hot oil, often with garlic, produces the tender-wilted, brilliantly coloured leaf that is one of the most characteristic Chinese vegetable preparations. The dish 蒜蓉菠菜 (suànróng bōcài, garlic-crushed spinach) represents the purest expression of this technique, in which the spinach is blanched for seconds and then tossed with raw crushed garlic and a small quantity of seasoning: no further cooking is needed, the residual heat of the spinach wilting the garlic and releasing its fragrance.
Damascus, Aleppo & the Abbasid Levant — c. 800 CE
The Levant is the hinge of this entire journey and the entry previously stepped over it. Spinach moved west out of Persia with the Arab expansion, and it was Arabic-speaking agronomists and cooks who carried it to Iberia; the plant arrived in Europe with an Arabic name, isbānākh, which became Spanish espinaca and from there every European word for it.
What the region did with it survives intact. Levantine spinach cookery is distinguished from every other tradition on this map by souring rather than enriching. Where Greece binds spinach with feta and Anatolia with white cheese, the Levantine preparations carry no dairy at all: the leaf is salted raw, wrung dry, and dressed with sumac, lemon, olive oil, and often pomegranate molasses. Fatayer bi sabanekh, the three-cornered spinach pastries sold by every bakery from Damascus to Amman, are the standard form, and sabanekh bi zeit, spinach stewed in oil with onion and chickpeas, is the everyday one.
The absence of dairy is not incidental. These are Lenten dishes for the Christian communities of Syria and Lebanon, where the fasting calendar excludes animal products entirely, and they belong equally to the Ramadan table. A cuisine with two long fasting traditions produces a great deal of very good vegetable cooking.
Seville & the Guadalquivir Valley, Al-Andalus — c. 1000 CE
The Arab agronomists who carried their knowledge of Persian horticulture westward across North Africa and into the Iberian Peninsula brought spinach with them as one of the most valuable additions to the Andalusian garden. By the 10th century CE, spinach was being cultivated in the irrigated kitchen gardens of Córdoba, Seville, and Granada, and the Andalusian agricultural literature reflects its established role: Ibn al-Awwam's Kitāb al-Filāḥa, written in 12th-century Seville, includes detailed guidance on its cultivation, noting its preference for cool seasons and moist soils. The same text describes the Arab culinary uses of spinach (braised with oil, combined with dried legumes, and seasoned with spices) that would pass into the Andalusian Spanish kitchen and survive in recognisable form to the present day.
The most celebrated Andalusian spinach dish, espinacas con garbanzos, is a direct descendant of this Arab-Moorish legacy. Spinach wilted in olive oil and combined with braised chickpeas, thickened with a bread picada and seasoned with cumin, coriander, paprika, and vinegar: the technique, the spice palette, and the combination are all unambiguously Arabised, and the dish is one of the clearest living examples of the Moorish contribution to the cuisine of southern Spain. It appears on tapas menus across Seville to this day, virtually unchanged in its essentials from the preparations described by Arab writers a thousand years ago.
From al-Andalus, spinach cultivation and the agricultural knowledge attached to it passed northward through the Christian kingdoms of Iberia and eastward into Norman Sicily, carried both by the agricultural exchanges of the Reconquista frontier and by the circulation of Arab botanical and agricultural texts through the schools of Toledo and Palermo.
Norman Sicily and the Arab-Norman Court at Palermo — c. 1100 CE
Norman Sicily between 1072 and 1194 was one of the most remarkable multicultural polities in medieval Europe: a kingdom where the Norman French lords, the remaining Arab and Berber Muslim population, and the Byzantine Greek communities lived in sufficient proximity that their languages, arts, and, crucially, their culinary knowledge flowed between them. The Arab gardeners of the Sicilian emirate (831–1072 CE) had cultivated spinach in the irrigated gardens around Palermo, and when the Normans conquered the island they retained both the gardeners and their knowledge. The court of Roger II at Palermo was genuinely trilingual (Norman French, Arabic, and Greek), and the agricultural and culinary knowledge held by Arab Sicily's farming population continued to be transmitted and practised.
From Sicily, spinach cultivation spread northward into the Italian peninsula along trade and diplomatic routes, and the combination of spinach with ricotta (pressed fresh curd cheese, a product of the pastoral economy of both Sicily and the southern Italian mainland) became one of the defining partnerships of the Italian kitchen. The spinach-ricotta filling for pasta, tarts, and pastries is a creation of medieval Italian cooking that reflects the Arab-Norman encounter: the leafy Persian-origin vegetable meeting the dairy tradition of the Italian countryside in a form that has proved extraordinarily durable across eight centuries of Italian culinary development. Ravioli di ricotta e spinaci, the filled pasta that is among the simplest and most universal preparations in the Italian repertoire, carries this history in its two core ingredients.
Tbilisi & the Georgian Caucasus — c. 1150 CE
Georgia sits directly on the road spinach took out of Persia, and it took the plant up early and completely. What the Caucasus then did with it has no parallel anywhere else on this journey, because Georgia thickens with walnuts where other cuisines thicken with dairy, oil, or flour.
Pkhali is the result and it is a method rather than a single dish: a vegetable cooked, squeezed bone dry, and pounded into a paste of walnuts, garlic, coriander, and vinegar, then served cool in mounds with pomegranate seeds pressed into the top. Spinach, beetroot, and aubergine are the classic three, set out together so the plate reads green, red, and near-black, and ispanakhis pkhali is the one most Georgians would name first.
The seasoning is what fixes it to this country and nowhere else. Utskho suneli, blue fenugreek, is a Georgian speciality sweeter and hayer than ordinary fenugreek, and dried marigold petals, imeruli saphrana, are used exactly where a Persian cook would reach for saffron, supplying colour and a faint bitterness at a fraction of the cost. Both are in the standard blend, khmeli suneli.
Spinach also goes into the Georgian soups and into the herb fillings of the region's breads, but it is the cold walnut paste that made the leaf a fixture of the supra.
The Courts and Monasteries of Medieval France and Northern Europe — c. 1350 CE
Spinach reached the kitchens of northern Europe through two converging channels in the 13th and 14th centuries. The first was the gradual northward diffusion of Mediterranean agricultural knowledge from Sicily and southern Italy, carried by trade, by the circulation of Arab botanical manuscripts through the cathedral schools, and by the movement of the Hohenstaufen court between Sicily and Germany. The second was the return of Crusaders from the Levant, where they had encountered the Arab use of spinach in Syria, Palestine, and Egypt; many returned with seeds, and the 'herb of Saracens' or 'Saracen vegetable' was a phrase used by several medieval European writers to indicate the plant's Islamic cultural origin.
By the mid-14th century, spinach appears in northern European recipe collections with a regularity that suggests it had become a familiar ingredient rather than an exotic curiosity. The English Forme of Cury (c. 1390), compiled by the cooks of Richard II, includes recipes for 'spynoches' (one of the earliest English written records) describing the leaf cooked with oil and onions in a manner that echoes its Arab preparation closely. French and German records of the same period record spinach in the monastery kitchen gardens, where its ability to grow in cool seasons and yield early in spring made it particularly valuable as a Lenten and fast-day vegetable when meat and dairy were forbidden. The torta di erbe tradition (savoury tarts filled with blanched greens, eggs, and cheese) is the medieval European synthesis of the Arab spinach tradition and the northern European herb pie, and it persisted in various forms through Italy, France, and England for several centuries.
Ottoman Anatolia and the Capital of Constantinople — c. 1400 CE
The Ottoman kitchen absorbed spinach from the Arab culinary world that had long been cultivating the plant in the eastern Mediterranean (in Syria, Palestine, and Anatolia) as an inheritance of the Abbasid agricultural tradition that had disseminated Persian agricultural knowledge across the Islamic world. When the Ottoman Turks established their empire across Anatolia and then seized Constantinople in 1453, they inherited a culinary world in which spinach (called 'ıspanak', adapted directly from the Arabic 'isfānāj') was already a familiar and valued ingredient. The Ottoman palace kitchen and the provincial cookery that descended from it developed the börek tradition as one of the supreme expressions of the Ottoman culinary achievement: sheets of ultra-thin filo pastry (yufka), hand-stretched to near-transparency, layered with fillings and baked or fried to a crisp. Among the most important börek fillings was the combination of spinach and white cheese (beyaz peynir), producing the 'ıspanaklı börek' that remains one of the most universally eaten savoury pastries in the Turkish, Balkan, and Levantine cooking traditions.
This Ottoman börek inheritance was the direct ancestor of the Greek spanakopita: the filo pastry technique, the spinach filling, and the cheese combination are all Ottoman in origin, introduced to the Greek-speaking world not from ancient Greece (which had no true spinach and no filo pastry) but through the centuries of Ottoman rule over the Aegean. This is not a diminishment of Greek cooking but an acknowledgement of the creative synthesis that took place: the Greek kitchen received these techniques and ingredients and made of them something unmistakably its own, with the spanakopita becoming as central to Greek food identity as the moussaka or the souvlaki.
Hanyang & Joseon Korea — c. 1450 CE
Spinach reached Korea from China, where it had been growing since the Tang embassy of 647, and the Joseon court agricultural manuals record sigeumchi as a cultivated vegetable by the fifteenth century. What Korea built around it is a treatment as brief and as exacting as the Japanese one, and quite unlike either.
Namul is the whole family of seasoned vegetable side dishes that make up the banchan of a Korean meal, and spinach is the most common of them. The leaf goes into hard-boiling salted water for thirty or forty seconds, no more, is dropped into iced water to fix the colour, squeezed dry, and then dressed rather than cooked: toasted sesame oil, garlic, a little soy, and sesame seeds crushed between the fingers as they fall.
The verb Koreans use is muchida, to dress and mix with the hands, and doing it with tongs is regarded as a small failure of care, because you cannot otherwise feel whether the seasoning has reached every strand.
Two things fix the dish in the culture. It supplies the green in a bowl of bibimbap, one of the five colours the bowl is built to show. And it is required at charye, the ancestral rites, where it is made with salt alone and no garlic at all, since strong alliums are excluded from ritual food, giving a paler and cleaner version of the same plate.
Renaissance Florence and the Medici Courts, Italy — c. 1533 CE
Spinach had been established in the Italian peninsula for several centuries by the time of the High Renaissance, carried northward from Sicily and from the Mediterranean agricultural tradition through the monastery gardens and the aristocratic kitchen. It was in the context of this already sophisticated Italian spinach culture that the story of Catherine de Medici (1519–1589) and French cuisine took shape. Catherine married the future Henry II of France in 1533 when she was fourteen; the legend that she brought Florentine cooks and Florentine spinach recipes to the French court, thereby civilising French cooking, is among the most durable narratives in culinary history, and almost certainly considerably embellished. Food historians have noted that French cuisine was already sophisticated before Catherine's arrival, and that most of the specific dishes attributed to her influence have French precedents.
What is clearly true is that the French culinary term 'à la Florentine' (applied to any dish served on a bed of wilted, buttered spinach, typically with a mornay or béchamel sauce) became firmly established in the French kitchen's vocabulary, and that it genuinely reflects some historical association between Florentine Renaissance cooking and the elevated use of spinach. Whether Catherine personally was responsible or whether the association reflects a broader Italian-French culinary exchange of the 16th century is of less consequence than the result: 'à la Florentine' became a permanent French culinary designation, and the preparation of creamed, buttered spinach as a rich under-layer for eggs, fish, and poultry became one of the foundations of the classical French kitchen. The oeufs à la Florentine (poached or baked eggs set on wilted spinach and finished with sauce mornay) is the simplest and most elegant expression of this tradition.
Innsbruck & Tirol, Austria — c. 1600 CE
The Alps turned spinach into a dumpling, which no other region on this journey thought to do.
The Knödel is the central preparation of Tirolean cooking and one of the great thrift dishes of Europe. Stale white rolls were never discarded in a mountain household; they were cubed, dried, and kept as Knödelbrot, soaked in warm milk when needed, and bound with egg, flour, and whatever the season gave. Spinatknödel is the spring and early summer version, and the quantity of squeezed spinach worked into the mixture turns the interior a deep marbled green.
The technique that decides it is the squeezing. Cooked spinach holds an extraordinary volume of water, and any left in will dissolve the bread to paste and the dumplings will break apart in the pan, which is why Tirolean cooks wring it in a cloth and then wring it again.
They are served two ways, both orthodox: floating in a clear beef broth with chives as a first course, or dressed with butter cooked to a nut brown and a heavy fall of grated hard cheese, which is what the mountain huts put in front of walkers.
The dish belongs to a region that a border cut in two. Tirol was divided in 1919 and its southern half became Italian, so Spinatknödel and canederli di spinaci are the same dumpling under two languages, and South Tyrol finishes them with Parmesan because South Tyrol is now in Italy.
Osaka & the Tōkaidō, Edo Japan — c. 1688 CE
Spinach reached Japan from China during the Edo period; the first clear evidence of cultivation in Japan dates to around 1688, recorded in Japanese agricultural texts of the Genroku era. The name the Japanese gave it, ほうれん草 (hōrensō), is of disputed derivation: one scholarly tradition connects it to a Japanese phonetic rendering of Persia (the country the plant ultimately came from, via its Chinese name's geographic reference to 'Boluo'), while another traces it to the Chinese agricultural route through which it arrived, though the plant's Chinese character-name (菠菜) would not straightforwardly produce the Japanese phonology. The etymology remains inconclusive, but the cultural adoption was swift and thorough.
In the Japanese kitchen, spinach found a use wholly unlike any of its Persian, Arab, Indian, or European expressions. The Japanese palate and the Japanese sense of culinary aesthetics (which prizes the clean, unmasked flavour of an ingredient, the careful balance of a simple dressing, and the presentation of colour and texture as the primary visual elements of a dish) directed spinach toward its definitive Japanese forms. The ohitashi (お浸し) preparation (spinach blanched for thirty to sixty seconds in boiling salted water, plunged immediately into cold water to preserve its vivid green, squeezed dry, and then soaked briefly in a dashi-based dressing of soy and mirin) produces a dish of extreme simplicity and delicacy, in which the quality of the spinach and the quality of the dashi are both entirely unmasked. Alongside it, the goma-ae (胡麻和え) preparation (the same blanched spinach dressed with a ground sesame paste sweetened with sugar and seasoned with soy) is the Japanese sesame's most celebrated application to a vegetable.
Greece and the Aegean World — c. 1700 CE
A necessary clarification before the Greek story begins: the ancient Athenians, the Alexandrian scholars, and the cooks of the Byzantine early centuries foraged and cultivated many edible greens under the collective Greek term horta (orache, mallow, nettles, sorrel, purslane, ground elder, and others) but none of these were Spinacia oleracea. True spinach did not reach the Aegean world until the Ottoman period, arriving through the Arab culinary tradition that the expanding Ottoman Empire had absorbed and systematised. The filo pastry technique that became central to Greek cooking is equally an Ottoman inheritance. This is not a diminishment of Greek culinary culture, which is one of the great and sophisticated traditions of the Mediterranean; it is simply an accurate statement of botanical history.
The spinach that Greeks eat today (and the spanakopita and spanakorizo that are among the most culturally significant foods of the modern Greek table) arrived through the Ottoman kitchen, which had in turn received it from the Arab agricultural tradition of Anatolia and the Levant. During the centuries of Ottoman rule over mainland Greece and the Aegean islands (roughly 1460 to 1821 for most of the mainland), the Ottoman börek tradition and the spinach-and-cheese filling that was among its most important forms were adopted and adapted by Greek-speaking communities, who made of them the spanakopita: a pie of filo sheets layered with a filling of wilted spinach, crumbled feta, eggs, and herbs, baked until the pastry is crisp and shatteringly flaky. The spanakorizo (spinach rice cooked in the Greek style with lemon juice, olive oil, and dill) represents the simpler domestic tradition, a weekday supper that requires only pantry ingredients and thirty minutes.
Virginia & New England, North America — c. 1720 CE
European settlers carried spinach seeds to the American colonies from the earliest decades of the colonial period, planting it in kitchen gardens alongside the other cool-season vegetables of the English, Dutch, and French domestic tradition. Spinach appears in the household records and cookery manuscripts of colonial America: Martha Washington's manuscript recipe book (compiled before and during her first marriage, c. 1749–57) contains spinach preparations, and the plant was clearly established as a domestic garden staple by the early 18th century. Its cool-season character suited the spring and autumn gardens of Virginia and New England, and the colonial spinach repertoire was broadly English in character: boiled and buttered, or incorporated into savoury tarts and pies in the manner of the medieval European herbolace tradition.
The American creamed spinach that became the canonical preparation of the 20th-century steakhouse, and of the home table that followed its fashions, is a simplified descendant of the French 'à la Florentine' tradition: spinach wilted and then stirred into a rich béchamel or cream reduction, seasoned with garlic, nutmeg, and salt. The steakhouse pairing (a slab of grilled beef alongside a ramekin of dense, creamy spinach) is one of the most American of all culinary combinations, and it has proved extraordinarily durable: creamed spinach appears on the menus of virtually every serious American steakhouse.
The cultural moment that most dramatically enlarged spinach's place in the American popular imagination came in 1929, when E. C. Segar gave his cartoon character Popeye the Sailor a seemingly magical appetite for tinned spinach, depicted as the source of sudden, explosive physical strength. The association was almost certainly a misapplication of a widely cited 19th-century German dietary study that had erroneously attributed to spinach an iron content ten times higher than it actually possesses. The error was eventually corrected, but not before Popeye had transformed the leaf's cultural status in the English-speaking world, and, remarkably, measurably increased its consumption in the United States for several decades.
Buenos Aires, Argentina — c. 1880 CE
South America is not spinach country, and the one substantial exception arrived by ship between 1880 and 1930.
Argentina absorbed one of the largest immigrations any country has taken in relative to its own population, and roughly half of the arrivals were Italian, from Liguria, the Veneto, Piedmont, and the south. They brought their vegetables and their kitchen with them, and the result is that Buenos Aires cooks more Italian than Spanish: milanesa, fainá, ñoquis eaten on the twenty-ninth of the month, and the whole family of tartas.
Tarta de espinaca is the most made of them, spinach cooked down with onion, bound with egg and cheese, and baked between two discs of pastry, often with a whole egg cracked into the centre so that one slice carries the yolk. It is in every rotisería window, at every family lunch, and cut cold into squares at every picnic.
The pastry says something about how domestic the dish has become. Argentine supermarkets sell tapas para tarta, ready-rolled discs, in shortcrust and puff, and almost nobody makes their own; cooks will tell you so without embarrassment.
That spinach holds its place here at all is the inheritance. The everyday cooked green across most of South America is chard, acelga, which is cheaper and hardier, and a great many Argentine households make the same tart with chard and give it the same name.
