I know that it is not very economic but always it comes well for some special occasion…
To set to warm a pot with water (the sufficient one to cover the barnacles) and fat salt.
When he boils we add the barnacles and a few leaves of laurel (depending on the quantity of barnacles).
When it returns to boil, we withdraw them from the fire and serve them warm covering them with a cloth in order that they do not lose the heat.
They can accompany on potato cooked in the same one it waters down in that we have cooked the barnacles.
Ah, I have to say to you that the tasty ones are small and rather fat …, and that this plate is grateful for a good wine…
