Caponata Siciliana
Sicily (especially Palermo)
Sicily's masterwork agrodolce vegetable stew: fried aubergine, celery, onion, and tomato combined with capers, green olives, pine nuts, sultanas, and wine vinegar-sweetened with sugar, then cooked together until everything melds to a complex, slightly saucy unified whole. Served at room temperature as an antipasto, with bread, or as a condiment alongside grilled fish. Every Sicilian household has its own recipe; the balance of sweet and sour is the fundamental variable. The dish improves dramatically over 24-48 hours.
