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.

Ingredients for bonito sorropotún for 4 people
- 1 kg of fresh albacore tuna, cut into cubes
- 2 medium onions
- 1 green pepper

How to make bonito sorropotún
Slice the day-old bread and toast it in 2 tablespoons of extra virgin olive oil. Set aside on absorbent paper until ready to use.

Dice the onion and, in the oil where we fried the bread, season with salt and pepper and sauté over low heat until it turns golden brown. This should take about 20-30 minutes.

Once the onion is well softened, add the diced bell pepper . Stir and cook for 2-3 minutes.

Add the roughly chopped potatoes. The starch they release will help thicken the sauce. Stir well to combine them with the onion and green pepper.

Cover with fish stock and simmer for 20 minutes until the potato is cooked.

Add the tuna and when it changes color, turn off the heat. It will cook for 3-4 minutes with the residual heat.

Add the fried bread slices. Serve in a plate or earthenware casserole dish sprinkled with chopped parsley or chives.
