Sorropotún de Bonito Fish Stew Recipe: Traditional Cantabrian Dish - grandgoldman.com
This page may contain affiliate links.

From San Vicente de la Barquera comes this fish stew called sorropotún de bonito. Bonito is an oily fish found in the cold northern waters and is in season between June and October.

It's a fish that can be prepared in various ways, such as pickled or cooked in marmitako. Sorropotún is the Cantabrian version of the Basque marmitako. A stew with all the intensity of the sea , traditionally eaten on fishing boats.

The recipe can vary depending on the family cooking it. Some versions include green pepper and tomato, while others don't. One of the most important steps for perfecting the recipe is the initial sautéing of the onion and the slow cooking of the bonito to ensure it retains its juiciness.
