After being caught, we select the best sardines, and the smallest ones, our favourites, we call “Sardinillas txikis” (“small” in Basque). We clean them meticulously by hand, removing the head and guts. Next, they are steam-cooked, in the traditional way, to achieve the desired texture and flavour. Finally, we place the small sardines into the tin one by one, by hand, so that their presentation is impeccable when opened. Then, we add olive oil, either on its own or with different hints of flavour: spicy, lemon, Espelette pepper...
To finish, the tins of small sardines go through a sterilisation process. This turns them into preserves and allows them to be kept in perfect condition for years and to develop even more flavour inside the tin.
