The periwinkles (Littorina littorea) also called magurios in the Basque Country and carmujos / caramuxos in Galicia are marine snails so their shell has the typical helical shape. Normally black, except for its entrance hole, which is white. They live in the middle of the rocks, feeding on algae. They have a hard membrane that protects them completely, closing the door that communicates them with the outside.
It is caught by hand in the rocks of the coast, and although it does not seem, the capture of this small species is also subject to a control of minimum sizes and plan of exploitation.
It has a lot of acceptance as an aperitif. They are simply cooked, for which it is necessary to have a pin that serves to extract its delicious meat, which is protected by a membrane that we must separate.
