Percebes — goose barnacles — are the strangest and most prized shellfish on the Portuguese coast: clusters of leathery stalks harvested by hand from rocks where the Atlantic breaks hardest, including the wild shore between Guincho and Cabo da Roca.
They are cooked simply — a brief boil in salted water, sometimes with bay leaf — and eaten with the fingers: twist, peel and bite. The flavour is pure, concentrated sea. Because the harvest is dangerous and regulated, they are priced as the delicacy they are, dearest in summer.
In Cascais they appear at the marisqueiras and the Guincho restaurants by weight; a small plate alongside a cold beer is the classic way in.
