About Kosher Salt

It became popular with American chefs in the late 20th century for its easy-to-pinch texture.

About French Grey Salt (Guérande)

The salt marshes of Guérande have operated continuously for over 1,000 years. The landscape of shallow ponds, channels, and dikes was engineered over centuries to optimize solar evaporation of Atlantic seawater. Paludiers, the hereditary salt harvesters, maintain the marshes and harvest salt using wooden rakes in a tradition protected as French cultural heritage. Gros Sel is the main commercial product-the heavy crystals that sink to the bottom of the ponds.

Best for: Cooking pot-au-feu, Salt-crusting fish, Boiling shellfish, Seasoning stews, Bread baking.
