About Rock salt

Rock salt is naturally occurring crystalline salt extracted from underground deposits and used as food salt when sold for culinary use. It can season food during cooking or at the table, and some coarse forms are used in salt grinders. The name does not establish a specific mineral composition, degree of refining, or whether additives are present.

Crystals can be clear, white, or coloured and range from fine grains to large chunks; colour and texture depend on the deposit and processing. Culinary forms include coarse crystals and milled salt. Nutrition comparisons depend on refinement, additives, and crystal size, since these affect the composition or the amount measured by volume.
