Bonito del Norte: 7 Recetas Tradicionales Vasco-Cantábricas
May 11, 2026
Quick summary: bonito del norte (Thunnus alalunga) is the albacore tuna from the Cantabrian Sea — it is fished between June and October with a rod and line, one by one, in the Bay of Biscay, and it is the raw material for the most emblematic recipes of the Basque Country and Cantabria. The 7 essential traditional recipes: marmitako (Basque stew with potatoes and peppers), Cantabrian salad (with piquillo peppers), escabeche (marinated tuna), tuna pie, grilled belly fillet, tuna salad, and tuna with tomato. All are made with quality canned tuna (Olasagasti, Ortiz, Serrats) or with fresh tuna in season.
Croquetas de Atún Cremosas: La Receta con la Bechamel Perfecta
May 11, 2026
Quick Summary: the best tuna croquettes have a thick but creamy béchamel sauce (ratio: 100g butter + 100g flour + 1 liter milk), at least 6 hours of refrigeration, an egg + fine breadcrumb coating, and frying at 175-180°C. Canned tuna in olive oil provides more flavor than natural tuna — for 1 liter of béchamel, use 250-300g of drained tuna. This recipe yields 35-40 croquettes. Active time: 40 min. Resting time: 6-24h. For 1kg BayMar light tuna belly, the flavor is strong; with Olasagasti trunk tuna, it's more refined.
