Himalayan salt is rock salt, or halite, mined from the Punjab region of Pakistan. The salt often has a pinkish tint due to mineral impurities. It is primarily used as a food additive, to replace refined table salt, but is also used as a material for cooking and food presentation, decorative lamps, and spa treatments.
Himalayan salt is used to flavor food. Due mainly to marketing costs, pink Himalayan salt is up to 20 times more expensive than table salt or sea salt. The impurities giving it its distinctive pink hue, as well as its unprocessed state and lack of anti-caking agents, have given rise to the belief that it is healthier than common table salt.
Slabs of salt are used as serving dishes, baking stones, and griddles, and it is also used on the rims of tequila shot glasses. In such uses, small amounts of salt transfer to the food or drink and alter its flavor profile. It is also used to make "salt lamps" that radiate a pinkish or orange hue, manufactured by placing a light source within the hollowed-out interior of a block of Himalayan salt.
