Also known as Black Salt.
Black salt (Hindi काला नमक kala namak) is an unrefined table salt with a strong sulphurous taste derived from the mixture of sulphur compounds with it.
Although it is indeed blackish as mined, the powder is more a light purple color.
Chemically, black salt is potassium chloride.
It tastes less salty than common table salt. Black salt is mined from quarries in Central Pakistan.
It is often used by people with high blood pressure or on low-salt diets because it does not contain significant amounts of sodium. (always consult your doctor first)
It is also believed to relieve both heartburn and flatulence.
Kala Namuk is used in Indian cuisine as a condiment and is added to chats, chutneys, raitas and many other savory Indian snacks. Kala Namuk has a hint of smokiness in its flavor.
