Yes, barnacles are edible and considered a delicacy, especially in certain regions like Galicia in Spain. They are crustaceans that are typically eaten cooked, not raw. The usual preparation involves boiling or grilling them for a short time, about 30 seconds to 1 minute, often in salted water to bring out their flavor. Barnacles are best eaten warm to enjoy their texture and taste fully. The edible part of barnacles, such as gooseneck barnacles, is the meat inside the muscular stalk or "foot." Their flavor has been compared to a mix between oysters and lobsters, with fresh saltwater notes, and their texture is initially crunchy then tender.
Barnacles require careful cooking to avoid undercooking or making them tough. Some people also sauté cooked barnacles briefly with lemon and olive oil. Harvesting barnacles is challenging due to their habitat in areas with strong waves, which is why they can be expensive and prized as a seafood delicacy.
