Spatola in Agrodolce con Cipolla e Uva Passa

Spatola in Agrodolce con Cipolla e Uva Passa is a Sicilian preparation of silver scabbardfish (often called spatola) in a sweet-and-sour sauce with onion and raisins. The dish draws on the island’s Arab-influenced culinary history, where the combination of vinegar, sugar, and dried fruit was common. Spatola is a long, silvery fish prized for its firm, white flesh and mild flavor; it is especially popular along Sicily’s southern coast.

Key ingredients are fresh spatola fillets, sliced onions, golden raisins (uva passa), vinegar (traditionally red wine vinegar), sugar, capers, and often pine nuts or bay leaves. The fish is typically floured and pan-fried until golden, then finished in the agrodolce sauce, which must achieve a precise balance between sharp acidity and sweetness. A great version features fish that remains moist and flaky inside, with the onions softened but not caramelized, and the raisins plump and tender without cloying the dish. The sauce should be glossy and just thick enough to coat each bite.

At Ristorante La Soglia in Seccagrande, Italia, chef Salvo Guarneri is noted for this preparation, using locally sourced Mediterranean spatola and Sicilian raisins. Regional variations substitute capers for olives, swap in Marsala wine for vinegar, or use amberjack or sea bream when spatola is unavailable. Some inland versions incorporate almonds or breadcrumbs for texture. The dish exemplifies Sicilian cucina povera, turning simple coastal ingredients into a refined balance of sweet, sour, and savory.
