Caponata

Sicilian sweet-and-sour eggplant relish: the agrodolce that tastes of the Mediterranean

Origin: Sicily, Italy

From the journey of Eggplant / Aubergine.

Caponata is Sicily's greatest contribution to Italian antipasto, a sweet-sour, slow-cooked eggplant relish enriched with celery, olives, capers, tomatoes, red wine vinegar, and sugar, which together produce the agrodolce (sweet-sour) flavour balance that characterises Sicilian and Arab-influenced Mediterranean cooking. It is a dish of extraordinary complexity that arrives at the table looking like a simple vegetable stew and reveals itself to be a masterpiece of calibrated flavour: simultaneously sharp and sweet, rich with olive oil, punched through with the brine of capers and olives, and underpinned by the eggplant's meaty, yielding body. Every Sicilian family has their version and defends it with conviction. Some add pine nuts and raisins, the Arab-influenced combination of sweet dried fruits and nuts in savoury dishes is distinctly Sicilian, a legacy of the Emirate of Sicily (9th–11th century CE) when the island was one of the most prosperous and culinarily sophisticated places in the Mediterranean. Some add anchovies for depth, some add cocoa powder (in the Palermo tradition) for a subtle bitterness, and in more elaborate coastal versions, octopus is added to create a seafood caponata of considerable distinction. The proportion of sweet to sour varies by city: Catanese caponata is sharper; Palermitano sweeter. The name 'caponata' is thought to derive from 'capone' (a Sicilian dialect word for lamprey or large fish) suggesting the dish may have originally been a sweet-sour sauce served over fried fish, in the manner of the sweet-sour fish preparations found across Arab-influenced Mediterranean cooking. Over time the fish disappeared but the sauce remained, reattached to the fried eggplant that had arrived with the Arabs centuries earlier. The agrodolce principle (balancing acid and sweet to create a third flavour that is neither) was a core element of Arab and medieval Mediterranean cookery, and Sicily, sitting at the crossroads of these culinary traditions, perfected it. Caponata is always served at room temperature (it is emphatically not hot food) and it improves dramatically overnight as the agrodolce flavours integrate and mellow. Great caponata, made with patience, tasted and adjusted until the balance is exactly right, and rested for a full day, is one of the most extraordinary things the Italian kitchen has produced.

Ingredients

Eggplant

  • 2 large eggplants (about 1kg total), cut into 2–3cm cubes
  • 3 tsp fine sea salt, for salting the eggplant

Frying

  • 1 litre vegetable oil, for frying the eggplant

Vegetables

  • 4 stalks celery, strings removed, cut into 1cm slices
  • 1 large onion, roughly chopped
  • 3 tbsp extra-virgin olive oil

Tomato

  • 400 g tinned crushed tomatoes

Agrodolce

  • 60 ml red wine vinegar
  • 1.5 tbsp caster sugar

Brine

  • 80 g green olives, stoned and halved (or Castelvetrano olives for a buttery style)
  • 2 tbsp capers, rinsed (salt-packed capers, rinsed well, are superior to brine-packed)

Nuts and Fruit

  • 30 g pine nuts, toasted in a dry pan until golden
  • 30 g raisins (optional but traditional in the Palermitano style)

Herbs

  • 4 fresh basil leaves, torn

Seasoning

  • 1 tsp salt, plus more to taste
  • 0.5 tsp black pepper

Method

  1. Salt the eggplant: place the cubed eggplant in a colander, toss with the salt, and leave for at least 30 minutes (up to 1 hour). The salt will draw out bitter liquid. Rinse thoroughly under cold water and pat completely dry with kitchen paper: the cubes must be genuinely dry before frying.
  2. Heat the vegetable oil in a deep pan to 180°C (350°F). Fry the eggplant cubes in batches (do not crowd the pan) for 3–4 minutes per batch, turning occasionally, until deep golden brown on all sides. Remove with a slotted spoon and drain on kitchen paper. The eggplant should be golden and completely tender.
  3. In a separate wide pan, heat the olive oil over medium heat. Add the onion and cook for 8 minutes until soft and beginning to colour. Add the celery and cook for a further 5 minutes: the celery should soften but retain a slight bite.
  4. Add the crushed tomatoes to the onion and celery. Season with salt and pepper. Cook over medium heat, stirring occasionally, for 10 minutes until the sauce has reduced and thickened.
  5. Add the red wine vinegar and sugar to the sauce. Stir to combine and let the mixture bubble for 2 minutes. Taste the agrodolce balance now: it should be distinctly both sweet and sour, with neither dominating. Adjust with a little more vinegar or sugar as needed.
  6. Add the fried eggplant cubes, olives, capers, raisins (if using), and most of the toasted pine nuts to the sauce. Stir gently to combine everything without breaking up the eggplant too much.
  7. Cook everything together over low heat for 5 minutes, stirring gently, until the eggplant has absorbed some of the sauce and everything is unified. Taste once more and adjust the sweet-sour balance, salt, and pepper.
  8. Remove from the heat. Allow to cool completely to room temperature. Transfer to a serving dish or storage container, scatter over the remaining pine nuts and the torn basil, and drizzle with a little extra olive oil.
  9. Rest the caponata for at least 2 hours before serving: overnight is strongly preferable. Serve at room temperature, never hot or cold straight from the refrigerator.

Notes

Caponata keeps refrigerated for up to five days and freezes well, making it ideal for preparing in large batches. Always bring it fully to room temperature before serving, cold caponata is flat and the oil congeals unpleasantly. The raisins and pine nuts are sometimes controversial outside Sicily but are historically correct and structurally important: they give the dish its Arab-influenced sweet-savoury dimension that distinguishes it from a simple eggplant sauce. Salt-packed capers, well rinsed, are noticeably superior to brine-packed for this dish. The Palermo tradition also adds a small square of dark chocolate (5g) or a teaspoon of unsweetened cocoa powder at the end, which deepens the sauce without making it taste of chocolate, a technique worth trying.

Solanum melongena

VegetablesNightshade Family (Solanaceae)

🌍Origin

Deccan Plateau & Western Ghats, South India — c. 2500 BCE

🌱Domestication

The eggplant is the one great vegetable of the nightshade family, the Solanaceae, to have come not from the Americas but from the Old World, and it stands quite alone amongst its relatives in this respect. Whilst the tomato, the potato, the chilli, and the sweet pepper all crossed the Atlantic eastward after 1492, Solanum melongena was already an ancient cultivated plant of monsoon Asia, domesticated from its wild and thorny ancestor Solanum insanum in the Indian subcontinent, most probably in the broad belt encompassing modern Karnataka, Maharashtra, and Gujarat that spans the Deccan Plateau and the Western Ghats. Archaeological and textual evidence places its cultivation firmly in South Asia by at least 2500 BCE, and the oldest Sanskrit names for the plant, amongst them vatinganah, confirm that early Indian farmers had already taken the small, bitter, hard-fruited wild species and, through patient selection, begun to coax from it the swollen, glossy, low-seeded fruit we know. That selection was extraordinarily fertile. From the single domesticated species an astonishing range of cultivated forms diverged across Asia: the long, slender, lavender Asian aubergines of the Chinese and Japanese kitchen; the small, round, green, and white Thai varieties bred for curries; the squat, deep-purple globe of the Mediterranean; the tiny, bitter pea aubergines of Southeast Asia; and the little white, egg-shaped sorts that gave the plant its English name. No other Old World vegetable shows such variety of shape, size, and colour, and that diversity records the antiquity and the geographical breadth of the plant's cultivation under human hands. The eggplant's defining culinary virtue lies in its spongy, fat-loving flesh. The raw fruit is dense, pale, and unpromising, faintly bitter, with a texture that can be unpleasant; but when it meets heat and oil it is transformed utterly, the open cellular structure drinking in fat, smoke, and seasoning and collapsing into something silky, unctuous, and deeply savoury. This generosity, the willingness to absorb whatever flavour it is given and to carry smoke and richness better than almost any other vegetable, is the quality that made it indispensable to the cooks of three continents. S. melongena belongs to the same botanical family as deadly nightshade and mandrake, the Solanaceae, and that kinship dogged it for centuries in the European imagination, where it was long held to be a maddening, even poisonous fruit; yet across Asia and the Islamic world no such suspicion attached to it, and there it became one of the most honoured of all vegetables, the canvas for some of the most sophisticated cooking in the world.

Global Voyage

From its South Asian cradle the eggplant travelled outward along the great trade arteries of the ancient and medieval world, carried not as a single wave but along several distinct corridors that between them spread the plant, and its Sanskrit-rooted name, across most of the inhabited earth. The first and most consequential corridor ran westward overland. From northern India the plant moved through the Khyber Pass into Afghanistan, the meeting ground of Indian, Persian, and Central Asian cooking, and on to the Persian plateau, where it reached the Sassanid Empire by the sixth century CE. The Persian word badinjan, descended directly from the Sanskrit vatinganah, became the linguistic seed from which almost every Western name for the vegetable would later grow, passing into Arabic as al-badinjan and thence into the Romance tongues. It was the Arab expansion and the Islamic Golden Age that carried the eggplant decisively into the Mediterranean. Arab agronomists and merchants, who prized the vegetable above almost all others, planted it across North Africa, in Al-Andalus, and in Sicily by the tenth century CE; the tenth-century Baghdad cookery book of Ibn Sayyar al-Warraq, the Kitab al-Tabikh, records thirteen distinct eggplant preparations, a measure of how central the plant had already become to the cooking of the Abbasid court. From Damascus and Baghdad the eggplant entered the kitchens of the Levant, where charring and mashing it with tahini and lemon produced baba ganoush; from Fez it entered the Moroccan cooked-salad tradition as zaalouk; and from the Emirate of Sicily it slipped into Italy, giving the Italian melanzana and, in time, the parmigiana di melanzane. A second corridor ran eastward. Along the Silk Road the eggplant reached China by the fifth century CE, where it became qiezi and, in the hands of Sichuanese cooks, the celebrated yu xiang qiezi; from China it passed to Japan during the Nara period to become nasu, hedged about with proverb and ceremony. A third corridor was maritime, the Indian Ocean and the Strait of Malacca, along which Tamil and later Srivijayan traders carried the plant to Sumatra, Java, the Malay Peninsula, and Thailand, where it became terong, terung, and ma-kheua, the structural heart of dishes from terong balado to kaeng khiao wan. The same Indian Ocean dhow routes that bore pepper and cardamom from Malabar carried the eggplant, through the great relay port of Aden, down the Swahili Coast to Zanzibar, where it became bilingani in a coconut curry that was at once Arab, Indian, and African. The Ottoman Empire then gathered up the whole Mediterranean and Arab inheritance and refined it into an imperial cuisine: the palace kitchens at Topkapi are said to have developed dozens of eggplant dishes, amongst them imam bayildi, and Ottoman influence carried these preparations across the Balkans and into Greece, where they were absorbed so completely that moussaka and melitzanosalata became Greek to the core. The plant reached the Americas with European colonisers in the sixteenth century, but its most poignant transatlantic crossings came later and by harder roads: enslaved and indentured peoples carried it with them, the Cape Malay communities transported to Table Mountain by the Dutch East India Company making it brinjal sambal, and Indian indentured labourers carrying the technique of flame-charring across the ocean to Trinidad, where baigan choka closed the circle and returned the eggplant, transformed yet unmistakably Indian at heart, to the New World.

🍽Modern Culinary Role

The eggplant is today one of the most widely cultivated and most versatile vegetables on earth, a cornerstone of cuisines that stretch in an unbroken band from Japan to Morocco and from the Caucasus to the Caribbean. Its singular culinary gift is its capacity to absorb: it drinks in fat, smoke, and seasoning with a generosity no other vegetable matches, and under heat its spongy raw flesh collapses into a silky, savoury, almost meaty richness that has made it, in many traditions, the favoured vegetable of those who eat little or no meat. That quality has given rise to an exceptional diversity of technique, for the eggplant is cooked in almost every way a vegetable can be: charred whole over flame and mashed, as in baba ganoush, baingan bharta, and baigan choka; sliced and fried then layered, as in parmigiana di melanzane and moussaka; braised slowly in oil until it dissolves, as in imam bayildi, zaalouk, and ratatouille; stir-fried with chilli and fermented bean, as in yu xiang qiezi; glazed with sweet miso, as in nasu dengaku; or stewed in coconut milk, as in the curries of the Swahili Coast and Thailand. That geographical reach is matched by a depth of cultural meaning few vegetables carry. In Bengal the eggplant sits on a pedestal of culinary affection; in Japan it appears in the New Year proverb that ranks it amongst the three most auspicious dream images; across the Arab and Mediterranean world it is the subject of more named, codified, and beloved dishes than almost any other plant. Its journey is also one of the most legible in all of food history, for the doubled naming of the vegetable, badinjan and its descendants flowing west out of Sanskrit, terong and brinjal flowing along the maritime routes, traces on the tongue the very trade corridors the plant followed. From the green curry of Bangkok to the caponata of Palermo, the eggplant remains the great absorbent canvas of world cooking, the vegetable that takes the flavour of wherever it has landed and makes that place taste more fully of itself.
