Mined from the volcanic regions of Himalayan Chain in Pakistan, black salt is a rock salt that is purplish/pinkish grey rather than black in color. It tastes mildly sulfurous and mineral, similar to hard boiled egg yolks, and is rich in iron. Use black salt as a condiment, rather than a cooking ingredient as you would use kosher salt. Crimson black salt is used extensively in international cusine as well as in Ayurvedic medicine. Crimson Black Salt has a distinctive taste. It is used in chutneys, raitas, provides the tangy fresh flavor in chat and many other snacks. It is often used by people with high blood pressure or on low-salt diets because it does not contain significant amounts of sodium. It is also believed to relieve both heartburn and flatulence. It is a great mix up of natural rock salt and herbals, which is unique in taste. It is available in shape of chunks, granules, lumps and fine powder etc. Different packing are available in it.
