One they have fully matured, Ortiz fillet the anchovies one by one using a knife and pack them carefully by hand in olive oil. Thanks to this meticulous preparation process, their anchovies have a compact texture and intense flavour.AboutOrtiz buy their Cantabrian anchovies daily from auctions along the north coast of Spain and process them the same day. They are put into salt for a period of 6-12 months depending on the size of the fish. When ready, they are gently washed, to remove excess salt, and the fish are trimmed and filleted by hand.
