Black salt, also known as kala namak, is a type of rock salt commonly used in Indian and South Asian cooking. It has a distinctive dark brown to black color with pinkish hues and a coarse texture. Unlike regular table salt, black salt has a unique, tangy, and slightly smoky flavor due to the minerals it contains, including iron and magnesium. It is often used in a variety of dishes such as chaats, salads, raita, and curries, adding depth and a savory taste. Black salt is also known for its potential health benefits, such as aiding digestion, reducing bloating, and promoting overall gut health. It is often considered a more natural and flavorful alternative to regular salt. Black salt is used both in cooking and as a seasoning, and its distinctive flavor makes it a favorite in many vegetarian and vegan dishes.
