Anchovies from the Cantabrica
Anchovies from the Cantabrian Sea are considered the best in the world: very thick, tasty and pulpy, as in this habitat they find the possibility of feeding abundantly and in well-oxygenated and cold water, which causes the fish to develop a delicate layer of fat, which it particularly affects the single taste.
This could be enjoyed as a starter with a burrata o fresh bread/butter.
