Marmitako de bonito

Basque Country, Spain

The bonito and potato stew of the Basque fishing boats — a one-pot dish built in layers using fresh bonito del norte (Atlantic white tuna), choricero peppers, potato, onion, tomato, and white wine. The name comes from marmita — the tin pot used on fishing vessels. The stew is the original sailor's lunch: everything available on a summer morning at sea. The potato is partially broken mid-cook — a technique called cascar la patata — which releases starch and thickens the broth without flour or roux. The bonito enters at the very end and finishes in residual heat. This sequence is non-negotiable.
