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.
