About Kona Deep Water Salt
Off the Kona coast of Hawaii's Big Island, cold deep ocean water rises close to the continental shelf. The Natural Energy Laboratory of Hawaii Authority (NELHA) pipes this pristine water from depths exceeding 2,000 feet for various applications. The deep water, part of a global thermohaline circulation pattern, has been cycling through the deep ocean for hundreds of years, accumulating minerals while remaining cold, nutrient-rich, and free from surface pollution.
Best for: Premium sushi, Sashimi, Raw seafood, High-end finishing, Japanese cuisine.

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.
