Edible salts, also known as table salts, are salts generally derived from mining (rock salt) or evaporation (including sea salt). Edible salts may be identified by such characteristics as their geographic origin, method of preparation, natural impurities, additives, flavourings, or intended purpose (such as pickling or curing).
Artisanal salts are produced using specific, often traditional, methods, resulting in unique flavor profiles and textures. They may be sourced from specific geographical locations, such as coastal regions or salt flats.
Geographical Indication (GI) salts are salts that can only be produced in a specific geographical area. These regions often have unique environmental conditions, such as soil composition, climate, or mineral content, that contribute to the salt's distinct characteristics. To protect their authenticity and quality, many are legally protected such as that of the EU's Protected Designation of Origin products.
