Sweet-and-Sour Aubergine

This classic sweet-and-sour aubergine, often known as caponata, is a cornerstone of Sicilian vegan cooking. Rich in texture and bold in flavour, the dish balances the earthiness of fried aubergine with the sharp tang of red wine vinegar and the brine of green olives and capers. Using sun-ripened Italian tomatoes and aromatic basil, it creates a deeply savoury base that improves significantly with time, making it an excellent option for advanced meal preparation.

As a versatile vegetable dish, it works beautifully as part of a Mediterranean mezze spread or served simply with crusty sourdough bread. For the best results, ensure the aubergines are well-drained and fried until perfectly golden, which provides the characteristic creamy centre. While satisfying enough to be a main course, it is traditionally served at room temperature to allow the complex sweet and savoury notes to shine.

How to make Sweet-and-Sour Aubergine

Cut aubergine into 1/2-inch cubes and transfer to a colander. Toss with 2 tablespoons sea salt. Let drain 1 hour.

While aubergine drains, heat 2 tablespoons oil in a 4- to 5-quart heavy pot over moderately high heat until hot but not smoking, then sauté three fourths of garlic, stirring, until golden, about 1 minute. Add tomato paste and cook, stirring, 1 minute. Add tomatoes with their juice, then reduce heat and simmer, uncovered, stirring occasionally, until thickened, 20 to 25 minutes.

Bring 725ml salted water to a boil in a 1- to 1 1/2-quart saucepan, then cook celery until tender, 5 to 7 minutes. Drain in a colander and rinse under cold water to stop cooking.

Gently squeeze aubergine to remove excess moisture and pat dry. Heat 1/4 inch oil (about 475ml ) in a 12-inch heavy skillet over moderately high heat until it registers 182°C on thermometer, then fry aubergine in 4 batches, stirring and turning constantly with a slotted spoon, until browned and tender, 3 to 5 minutes per batch. (Return oil to 182°C between batches.) Transfer to paper towels.

Pour off all but 2 tablespoons oil from skillet, then reduce heat to moderate and cook onion, pepper, and remaining garlic, stirring occasionally, until golden, about 10 minutes. Add tomato sauce, aubergine, celery, olives, capers, vinegar, sugar, pepper, and remaining teaspoon sea salt and simmer, uncovered, stirring occasionally, 15 minutes. Cool to room temperature, uncovered, then chill, covered, at least 8 hours.

Just before serving, stir in parsley and basil. Serve cold or at room temperature.
