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.

Australia's interior contains thousands of salt lakes formed when ancient seas receded millions of years ago. The continent's flat, arid interior with minimal rainfall preserved these salt deposits. Lake Eyre (Kati Thanda), Australia's largest lake, is a salt flat that fills with water only rarely. Aboriginal Australians harvested salt from these lakes for thousands of years. Commercial salt production began in the 19th century and today Australia is a major global salt exporter, particularly for industrial and food-processing markets.
Best for: General cooking, Industrial use, Table salt, Water softening, Food processing.
