Yellowfin is a species of tuna sought after for its delicate flavor and meaty texture. To make these jars of succulent fillets, IASA completes every step by hand just as they have for decades. First, yellowfin tuna is sustainably caught off the Amalfi Coast, after which the entire fish is slowly steamed to lock in its moist tenderness. Finally, the fillets are packed into glass jars with high-quality olive oil to imbue an extra dose of richness and preserve the tuna’s firm bite.
