Albacore tuna belly in olive oil Costera, presented in a 120 gr format. The belly, also called ventresca, is the part of the tuna known for its juiciness and tenderness. This preserve is made fresh and by hand during the Cantabrian Bonito fishing season, which takes place in the summer months. It is produced by Conservas Costera, a family-run cannery from Gijón, which presents this specialty as a gourmet option for the table. The production process preserves the flavor and juiciness of this cut of fish. The product information indicates a best-before period of 6 years, during which these qualities are maintained. Tuna and olive oil define this preserve, combining the softness of the ventresca with an artisanal preparation linked to the summer season of the Cantabrian Sea.
