Rinse and fillet at home:
1. Soak the anchovies in cold water for 10 minutes then clean under running water, rubbing the salt off with your fingers.
2. Open the anchovy from the top half of the fish while it is still under the tap.
3. With the help of your thumb, separate the two anchovy fillets.
4. Remove the bone and finish cleaning.
5. Dry the anchovies lightly with a cloth, lay them in a container and cover them with olive oil.
