Cancale oysters are a renowned variety of oysters harvested from the coastal waters of Cancale, a small town in Brittany, France. These oysters, scientifically known as Ostrea edulis, are celebrated for their unique flavor, which is influenced by the region's rich marine environment and tidal variations. The oysters are typically harvested during the colder months, ensuring their freshness and quality. They are often enjoyed raw on the half shell, accompanied by lemon or vinegar, making them a popular delicacy among seafood lovers and a staple in French cuisine.
