What Is Black Salt?
Black Himalayan salt, also known as kala namak, is a common condiment used in South Asian cooking. It is typically mined from the foothills of the Himalayan mountains in countries such as Pakistan, Nepal, India and Bangladesh. Although some varieties are dark in color, others may range from brownish-pink to violet.
The black salt formula consists of chemical compounds such as sodium chloride, sodium sulfate, ferrous sulfate, magnesia, ferric oxide and greigite. Thanks to its high sulfur content, it has a pungent smell and savory flavor that works well in chutneys, salads and savory snacks.
In traditional forms of medicine, such as Ayurveda, this type of salt is said to have a cooling effect on the body. It has also been used as a natural remedy to treat a range of ailments, including heartburn, gas and muscle cramps.
