About Persian Blue Salt

Persian blue salt is one of the rarest salts on earth. It is found only in a few salt mountains in Iran's Semnan province. The blue coloration occurs when the halite crystal lattice is compressed under extreme geological pressure over millions of years, causing a structural change called sylvinite that refracts light to appear blue. Annual production is only a few tons.

Best for: Finishing seafood, Foie gras, Truffle dishes, Desserts, Specialty cocktails.

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.
