Wikipedia Article About Black salt on Wikipedia Black salt (Hindi काला नमक kala namak) is an unrefined table salt with a strong sulphurous taste. Contrary to what its name suggests, it is pink in colour and has only a faint salty taste (due to its high mineral content) . It is used extensively in Indian cuisine as a condiment as well as in ayurvedic medicine and is commonly sold in the form of a fine, almost completely odorless powder.
