Fleur de sels are flat grains of the sea flower known as Sea fleur-de-lis, also known as sea foam. Fleur de sels have a texture similar to seaweed. They are produced by microorganisms living in the sea waters, and are the salts of life on earth. The name fleur de sel comes from the Latin word for “sea flea”. These salty, soft grains are harvested from the coasts of Western Europe, the Mediterranean, the Bay of Niles, and the Black Sea.
