Remove the skin and bones from the tuna. Place these into a strainer and rinse to remove any scales or blood.

Make a fish stock by sweating gently with a drop of olive oil all the vegetables for 5 minutes, add the fish bones and cover with water. Bring to the boil, skim all impurities and simmer for twelve minutes, strain through a fine sieve and set aside.

​

Chop the red onion and green peppers finely, cut the potatoes into irregular 4cm chunks. The best way is to cut into the potato and then break it off with the knife as this helps release the starch which in turn will help thicken the stew.

​

Pour 2 tbsp of extra virgin olive oil into a large pot, heat slowly and add the red onion and green peppers, when the onion is soft add the potatoes and stir with a wooden spoon, cook slowly for 5 minutes to allow the potatoes to release their starch.

​

Place a fine strainer over the pot and pour the fish stock to cover the potatoes, if necessary add a little water. Bring to the boil and cook on a moderate heat moving the pot now and again for the potatoes to thicken the stew. Season with salt and add the pimiento choricero.

​

The potatoes should take about 15 minutes to cook at a slow heat. Cut the tuna into one 2cm chunks, once the potatoes are cooked add the fish and cook for about 2 or 3 minutes turn off the heat and put a lid on the pot and leave for 5 minutes to rest.

 

Serve immediately & Bon Apetit!
