Foeniculum vulgare Mill., a perennial of the Mediterranean basin grown in three quite different ways from one species. Var. vulgare is common or bitter fennel, raised for its seed and its feathery foliage; var. dulce is sweet fennel, milder in the seed and the source of most fennel used as a herb; and var. azoricum is Florence fennel or finocchio, selected in Italy for the swollen overlapping leaf bases that form the bulb eaten as a vegetable.
Fennel is native to the shores of the Mediterranean and grows wild there still, on roadsides and waste ground and cliff edges, tall and feathery and smelling of aniseed when crushed. It required very little from anybody to become useful: the whole plant is edible, the seed keeps indefinitely, and it self-seeds so readily that the line between gathering it and growing it has never been sharp. Much of the fennel used in Sicilian and Cretan cooking today is still picked rather than farmed.
What happened over time was not domestication so much as division. One species has been pulled in three directions by selection, and the three results behave as different ingredients in the kitchen. Common or bitter fennel, var. vulgare, is grown for seed and foliage and is the plant of the wild hillsides. Sweet fennel, var. dulce, is milder and greener and supplies most of what is sold as fennel seed and fennel herb. Florence fennel, var. azoricum, is the vegetable: selected in Italy for leaf bases that swell and overlap into a dense white bulb, it is eaten raw, braised, or roasted, and its seed is an afterthought.
The atlas therefore gives fennel two origin points. The first is the Mediterranean home of the species, where the wild plant grows and where its seed and fronds entered cooking in antiquity. The second is Tuscany and Emilia in the sixteenth and seventeenth centuries, where the bulb variety was selected out of that same species and became a vegetable rather than a spice. The second is an origin of a variety rather than of a plant, and the entry says so rather than blurring the two.
The seed is not a seed. What is sold as fennel seed is the dried schizocarp, the paired fruit of the flower head, which splits into two ribbed halves called mericarps; this is true of the whole family, and it is why coriander, cumin, caraway, and fennel all look faintly alike and all split the same way. Left on the plant a little longer, the fruits ripen from green to grey-brown and lose the bright grassy note that fennel pollen, harvested from the flower head before the fruit sets, retains in concentrated form.
Fennel moved along every trade road that mattered and settled into a different job at the end of each of them, which is unusual even amongst spices.
Going east, it reached Persia early and travelled on with the caravan trade into India and along the Silk Road into China. India took it more thoroughly than anywhere else on earth: Gujarat and Rajasthan are now the largest producers of fennel seed in the world, and saunf runs through the whole subcontinental repertoire, whole in pickles and panch phoron, ground into the base of a Kashmiri yakhni, and sugared as mukhwas to be chewed after a meal. China gave it a name that records the confusion it caused: 茴香, huíxiāng, returning fragrance, with fennel as 小茴香, the small one, and star anise, an entirely unrelated plant, as 大茴香, the big one. Fennel is one of the five in five-spice, and northern China does something almost nobody else does, chopping the fresh fronds by the handful into dumpling filling and treating them as a green vegetable.
Going west and south, it went with Rome across the empire and then again with the Arab expansion into the Maghreb and Al-Andalus, which is why fennel turns up in ras el hanout and in the Moorish fig breads of Andalusia. Provence built it into the fish kitchen, where dried fennel stalks are burned under a sea bass and fresh fennel goes into a bouillabaisse.
And then the varietal split sent it in a direction none of the others had taken. Once Italy had a bulb rather than a herb, fennel became a vegetable, and it travelled as one: to England by the 1720s, to the Americas with Italian emigration, and onto the produce shelves of countries that had never used the seed at all. The name records a puzzle on the way. The varietal epithet azoricum points at the Azores, and Florence fennel is not from the Azores; it appears to be one of those eighteenth-century botanical names that records where a European naturalist met a plant rather than where it came from.
India dominates the seed. Gujarat and Rajasthan together account for the great majority of world production, most of it consumed domestically, and the crop is a fixture of the semi-arid rotation there. Egypt, China, Turkey, Syria, and Bulgaria supply most of the rest, and the bulb is a separate industry altogether, grown intensively in Italy, Spain, and increasingly in California and Australia for a market that treats it as a salad vegetable.
The plant carries a chemical that explains most of its history. Anethole is the compound responsible for the sweet liquorice note in fennel, and it is also the dominant aromatic in anise and in star anise, three plants from three unrelated families that taste alike because they arrived at the same molecule independently. That convergence is why the three are so often confused, why they substitute for one another in cooking, and why they appear together in the anise spirits of the Mediterranean: pastis, ouzo, raki, and absinthe all use one or more of them, and absinthe traditionally uses fennel alongside anise and wormwood.
Fennel has a long medical history and a good deal of it is folklore. The seed has been used against colic, indigestion, and hunger for as long as there are records, and gripe water for infants was built on it. Some of that has a mechanism, since anethole is mildly antispasmodic, and some of it does not: the tradition that fennel restores eyesight, repeated from Pliny through the medieval herbals on the grounds that snakes rub against it to clear their eyes, is folklore outright and was carried for fifteen centuries on the strength of a story about snakes.
One caution about naming, because the confusion is old and occasionally consequential. Giant fennel is Ferula communis, a different genus that grows in the same Mediterranean scrub, and it is toxic. It is the narthex of Greek myth, the hollow stalk in which Prometheus is said to have carried fire down from Olympus, and the plant whose pith really was used as tinder and as a splint. It is not the fennel of this entry and should not be gathered as though it were.
Historical Journey of Fennel
Marathon, Attica & the Aegean — c. 3000 BCE
Fennel is native to the Mediterranean shore and grows wild across Greece still, and the Greek language settled the matter of where it belongs by naming a place after it. Marathon is the Greek word for fennel, and the plain of Marathon in Attica means the place where fennel grows. The battle fought there in 490 BCE therefore carries the plant's name, and the modern race carries the battle's, which makes the marathon the only athletic event on earth named after an umbellifer.
Greek cooking uses the wild plant rather than a farmed one, and it uses the fronds. Cretan marathopita is a pie of wild fennel and greens gathered from the hillsides in spring, folded into a thin oil pastry and fried on a griddle, and it belongs to the horta tradition, the eating of wild greens that is one of the oldest continuous food practices in Europe. Loukaniko takes the seed instead, curing coarse pork with fennel and orange peel into the sausage of the mainland and the islands.
One correction belongs at the origin, because it has travelled further than the plant. Prometheus is regularly said to have carried fire down from Olympus in a fennel stalk. The Greek word is narthex, which is giant fennel, Ferula communis, a different genus with a hollow pith that genuinely does smoulder slowly and was used as tinder. It is also toxic. The two plants grow in the same scrub and have been confused in translation for two thousand years.
The Nile Valley & Egypt — c. 1550 BCE
Fennel appears in the Ebers Papyrus, the Egyptian medical compilation of around 1550 BCE, amongst a long list of plants prescribed for the stomach, and it has been grown in the Nile valley ever since. Egypt remains one of the larger producers of the seed and shamar is still the everyday Arabic word for it there.
Its use in Egypt has stayed closer to the medicine chest than the kitchen, which is why this point marks a passage rather than a cuisine. Fennel tea is drunk for digestion and for nursing mothers across the Arab world, and the practice is old enough and continuous enough to be documented at both ends of the record. What Egypt principally did for fennel was pass it on: north into the Levant, east into Persia, and later west along the whole southern shore of the Mediterranean with the Arab expansion.
Isfahan & the Iranian Plateau — c. 500 BCE
Persian rāziyāna is the hinge on which fennel's eastern journey turns. From the Iranian plateau the plant and its name went in two directions at once: south-east with the caravan roads into the Indian subcontinent, where rāziyānaj became the Arabic and then, by other routes, the Hindi saunf; and north-east along the Silk Road towards the Tarim basin and the Chinese interior.
Persia itself uses fennel lightly compared with what lay at either end of those roads, in herb mixtures and in the seed blends chewed after a meal, which is why this point records a passage rather than a cuisine of its own. What matters here is the fork: almost everything fennel became in Asia, and it became a great deal, went through this plateau first.
Rome & the Roman Empire — c. 100 BCE
Rome is where fennel becomes a written ingredient rather than a gathered one. Apicius uses it in seasoning mixtures and in the spiced wines; Pliny gives it a long entry in the twentieth book and repeats the claim that snakes eat it to clear their eyes after shedding, which launched fifteen hundred years of the belief that fennel is good for the eyesight and never acquired any evidence at all.
The Roman contribution was distribution. Fennel went out along the roads and the garrison gardens into Gaul, Iberia, Britain, and North Africa, and the Latin name went with it: faeniculum, little hay, from the smell of the dried plant, which produced Italian finocchio, French fenouil, Spanish hinojo, Portuguese funcho, and English fennel. The whole Romance west calls this plant by a word meaning hay.
The seed was also used the way we now use a mint: fici farsi, figs split and stuffed with nuts and fennel seed, belongs to that Roman habit of finishing on something aromatic, and the dish survives in southern Italy essentially unchanged.
Ahmedabad, Delhi & the North Indian Plain — c. 100 CE
India took fennel further than anywhere else on earth. Gujarat and Rajasthan between them now grow the great majority of the world's fennel seed, most of it eaten within the country, and saunf is one of a handful of spices that turns up in essentially every regional kitchen of the subcontinent in some form.
It has three quite separate jobs. Whole, it goes into pickles and spice bags: the potli masala of Old Delhi nihari, the Rajasthani ker pickles, the mango achar of the north. Ground, it becomes the sweet backbone of a whole family of gravies. And on its own, roasted and sugared, it is mukhwas, the mouth freshener set out in a dish by the door of every Indian restaurant and carried in a tin by a great many households, which is a use of a spice that has no real parallel anywhere else.
Gujarat also drinks it. Variyali sharbat steeps fennel seed with sugar into a pale green cordial served cold through the hot months, and the reasoning behind it is the same reasoning behind the mukhwas: fennel is classed as a cooling spice in the Ayurvedic scheme, and Gujarat is very hot for a long time each year.
Chang'an, Xi'an & the Northern Chinese Plain — c. 200 CE
Fennel arrived in China along the Silk Road and was given a name that records exactly the confusion it caused. 茴香, huíxiāng, means returning fragrance, and Chinese then had to separate it from an unrelated native plant that tastes remarkably like it: fennel became 小茴香, small returning fragrance, and star anise 大茴香, big returning fragrance. The two belong to different families and share only anethole, the compound that gives both their liquorice note.
Northern China then did something with fennel that almost nobody else does. The fresh fronds are treated as a leaf vegetable rather than a herb, chopped by the handful into dumpling filling with pork and sesame oil; huíxiāng jiǎozi are a fixture of the household kitchen from Shandong through Hebei to Shaanxi, and the quantity of greenery in them is startling to anyone who thinks of fennel as a seed.
The seed took the other road and went into the braise. Jiàng niúròu, beef simmered in a dark soy master stock, carries fennel amongst its aromatics, and from the northern braising tradition the spice worked south into the blends that made it famous.
Kolkata & the Ganges Delta — c. 400 CE
Bengal put fennel into a blend and then built a cuisine on it. Panch phoron is five whole seeds in roughly equal measure, fennel, cumin, black mustard, fenugreek, and nigella, and it is unusual amongst Indian spice mixtures in three ways: it is never ground, it is added whole to hot oil at the start of cooking rather than at the end, and its composition is fixed rather than a matter of household preference.
The sequence in the pan is the skill. The five seeds have quite different sizes and oil contents and therefore quite different burning points, and a cook who tips them in together and waits will have burnt the mustard before the fenugreek has opened. Fenugreek in particular turns bitter within seconds of going too far, and Bengali cooks watch for it specifically.
What the blend does is give Bengali vegetable cooking its particular signature: a sweetness from the fennel against the bitterness of the fenugreek and the nigella, which is the same sweet-and-bitter balance that runs through the whole Bengali meal and reaches its clearest expression in shukto. Panch phoron crosses the modern border without noticing it and is as much Bangladeshi as Indian.
Srinagar & the Vale of Kashmir — c. 700 CE
Kashmiri cooking is built on a small set of ground spices used in quantities that would be unusual anywhere else, and fennel is the largest of them. Saunf powder goes into a yakhni by the tablespoon rather than the teaspoon, alongside dried ginger, and between them they do the work that onion and garlic do in most Indian cooking.
That absence is the point. The Kashmiri Pandit kitchen traditionally uses no onion and no garlic at all, for reasons of ritual purity, and it needed a substitute for the sweetness and body those two supply. Ground fennel and dried ginger, saunf and sonth, are what it settled on, and the pair defines the flavour of the entire cuisine: they are in the yoghurt-based yakhni, in rogan josh, in dum aloo, and in shab deg, the long-cooked turnip and meat pot left overnight in a sealed vessel.
It is one of the clearest cases anywhere of a religious restriction producing a flavour, and the flavour outlasted the restriction: Kashmiri Muslim cooking uses onion freely and keeps the fennel anyway, because by then it was what Kashmiri food tasted like.
Beirut & the Levant — c. 900 CE
Fennel and anise are treated as near neighbours in Levantine baking, and the pair turns up together in the sweet breads and semolina cakes of the Lebanese mountain. Sfouf, the turmeric-yellow semolina cake of Mount Lebanon, carries both, and the seeds are as often chosen for what they do to the smell of the kitchen as for the taste of the finished thing.
The Levant is also where fennel joined the westward Arab movement. Under the Abbasids and afterwards, the seed travelled with the whole apparatus of Arab cooking along the North African coast and into Sicily and Al-Andalus, which is why fennel appears in ras el hanout and in the Moorish fig confections of Andalusia rather than arriving there separately from Rome.
Guangzhou, Fujian & Lingnan — c. 950 CE
Southern China turned fennel into an institution by putting it in a blend that carries its own arithmetic in the name. Wǔ xiāng fěn, five-spice powder, is star anise, cassia, clove, Sichuan pepper, and fennel, and fennel is the one amongst them doing the sweetening; take it out and the blend turns sharp and medicinal.
The blend belongs to the southern braising tradition rather than to stir-frying. Lóushuǐ, the Cantonese and Chaozhou master stock, is a standing pot of soy, rock sugar, wine, and whole spices that is topped up and re-boiled for years and sometimes for generations, and fennel is one of the fixed aromatics in it; everything from soy-sauce chicken to braised goose passes through it. Sìyóugāi, soy sauce chicken, is what that stock produces at its simplest.
From Lingnan the blend went wherever southern Chinese emigration went, which is a great deal of the world, and it carried fennel into the braising pots of Southeast Asia along with it.
Fez, Marrakesh & the Maghreb — c. 1000 CE
Fennel reached the Maghreb along the southern shore with the Arab expansion and settled into the spice cupboard rather than the vegetable garden. Its most conspicuous home is ras el hanout, the blend whose name means head of the shop and which is not a fixed formula at all but a merchant's signature: a good one runs to twenty or thirty spices and each seller guards the proportions.
Fennel in that blend does what it does in five-spice on the other side of the world, supplying a sweet aromatic base under the sharper and more expensive things. Wild fennel is also gathered across the Atlas foothills and the Rif and cooked with beans and with fish along the coast, which is the same use the northern shore makes of it and probably the older one on both sides.
Palermo & Sicily — c. 1100 CE
Sicily uses wild fennel, finocchietto selvatico, and uses it as a vegetable rather than a seasoning. It grows unattended across the island, it is gathered rather than farmed, and it goes into the dish that is as close to a Sicilian emblem as anything: pasta con le sarde, in which the fronds are boiled, chopped, and cooked with sardines, saffron, raisins, and pine nuts, and the pasta is finished in the fennel's own cooking water.
That combination is a straightforward record of the Arab period. Sicily was under Muslim rule from the ninth century to the eleventh, and the raisins, the pine nuts, the saffron, and the sweet-savoury logic of the whole dish come from that kitchen, laid over a Mediterranean plant and a Mediterranean fish. Very few dishes anywhere state their own history so plainly.
The island also eats fennel raw and cold against citrus, in the winter salad of sliced oranges, fennel, olives, and raw onion that appears on every Sicilian table from December to March, when both are at their best at the same moment.
Marseille & Provence — c. 1300 CE
Provence attached fennel to fish and has never really let go. Dried fennel stalks are burned under a whole sea bass so the smoke perfumes it from below, sometimes with a splash of pastis thrown on to flame; fresh fennel goes into the pot of a bouillabaisse along with the saffron and the orange peel; and dried fennel seed is one of the constants of herbes de Provence, which is the one blend in the mixture that most reliably tells you the cook is south of Lyon.
The region also drinks it. Anethole is the aromatic that fennel shares with anise and star anise, and the anise spirits of the Mediterranean are built on one or more of the three: pastis in Marseille, and absinthe before it, which traditionally used fennel alongside green anise and wormwood. That fennel, anise, and star anise come from three unrelated families and taste alike is one of the tidier accidents in botany, and the drinks cabinet of the whole Mediterranean rests on it.
Seville, Andalusia & the Iberian Peninsula — c. 1400 CE
Fennel arrived in Iberia twice, once with Rome and again with Al-Andalus, and the second arrival is the one the food remembers. Pan de higo, the pressed fig cake studded with almonds and fennel seed, is a Moorish sweet that outlived the kingdom that produced it and is still made across Andalusia and Extremadura; the fennel in it is doing the same work as in Roman fici farsi, a thousand years and one civilisation apart.
The wild plant is gathered and eaten as a vegetable in the south, particularly in spring, when hinojo goes into pots of broad beans and chickpeas and into the brine with capers and caper berries. Habas con hinojo is the plainest version: young broad beans stewed with wild fennel, garlic, and olive oil, which is a dish of three ingredients and a season.
Florence, Bologna & Tuscany — c. 1550 CE
This is fennel's second origin, and it is the origin of a vegetable rather than of a plant. Italian growers in Tuscany and Emilia selected Foeniculum vulgare for leaf bases that swelled and overlapped at ground level into a dense white bulb, and by the seventeenth century finocchio was an established garden vegetable rather than a herb. It reached England by the 1720s and the rest of the world with Italian emigration, and a great many countries now buy fennel as a salad vegetable without ever using the seed.
The varietal name records a puzzle. Var. azoricum points at the Azores, and Florence fennel is not from the Azores; it appears to be one of those eighteenth-century botanical names that records where a European naturalist happened to meet a plant rather than where it came from.
Tuscany kept the seed as well and put it into pork. Finocchiona is the Tuscan salami cured with wild fennel seed, and the usual story is that it was born of theft, fennel having been used to cover the flavour of doubtful meat or, in a second version, to mask a poor wine at a fair; the Italian expression infinocchiare, to hoodwink, is generally traced to it. The etymology is repeated everywhere and demonstrated nowhere, and it is a good story either way. The bulb, meanwhile, is baked under béchamel as finocchi gratinati, and the seed goes into arista, the Florentine roast pork loin.
São Miguel, Madeira & the Portuguese Atlantic — c. 1600 CE
Fennel went out into the Atlantic with Portuguese settlement and found the islands entirely to its liking. It naturalised on the Azores and on Madeira so thoroughly that it now grows wild across both, and funcho is embedded in the local vocabulary: Funchal, the capital of Madeira, is named for it, the settlers having found the hillside above the bay covered in fennel when they landed in the 1420s.
The Azores turned it into soup. Sopa de funcho is a São Miguel dish of wild fennel cooked with potato, beans, and a little pork or chouriço into something between a broth and a stew, and it belongs to the Espírito Santo festivals as much as to the everyday table. Madeira put the seed into its baking instead, and bolo de mel, the dark spiced sugarcane-molasses cake that keeps for a year, carries fennel amongst its spices.
The islands also explain, or fail to explain, a name. The bulb variety of fennel carries the botanical epithet azoricum and did not come from here, which remains one of the more cheerful loose ends in the plant's nomenclature.
Hanoi, Nam Định & Northern Vietnam — c. 1800 CE
Fennel came south into Vietnam with the Chinese braising spices and settled into the one dish the country is known for above all others. The spice bag of a phở broth is star anise, cassia, clove, coriander seed, black cardamom, and fennel, dry-toasted before it goes into the pot with the charred ginger and onion, and the fennel is there to round the sharper edges of the star anise.
Northern Vietnam is where the dish was assembled, in Nam Định and Hanoi around the turn of the twentieth century, out of Vietnamese rice noodles, Chinese aromatics, and the beef bones that French colonial butchery left over. Fennel is a small part of that and a fixed one, and a pho broth built without it is noticeably harsher.
Durban & the Colony of Natal — c. 1860 CE
Fennel reached South Africa in the spice tins of indentured labourers. From 1860 the Colony of Natal recruited workers from Madras, Calcutta, and the north Indian plain for the sugar estates, and the masalas they brought with them became, over a century and a half, a distinct Durban style: hotter than most Indian regional cooking, heavier on chilli and on ground coriander, and built on blends sold loose by weight in the Victoria Street market.
Fennel is one of the constants in those blends and one of the few sweet notes in them. It is in the curry powder that fills a bunny chow, the quarter loaf hollowed out and filled with curry that Durban invented under conditions worth stating plainly: Indian shopkeepers were barred from serving black customers indoors and passed the food out through a hatch in something disposable, so the vessel was a loaf.
