The European Flat (Ostrea edulis), also known as a Belon, is the native oyster of Europe. It’s related to the Olympia, but has a much larger size and an even stronger flavor of smoke and metal. Love it or leave it. It’s hard to cultivate, and is thus usually harvested wild. Best places to still find it are Brittany, Ireland, and Maine. Once you discover your favorite species, you can use the Explore feature to find new favorites.
