Black salt, also known as *kala namak*, is a distinctive spice commonly used in Indian, Middle Eastern, and Southeast Asian cuisines. It is a type of rock salt that has a dark brownish-black color due to the presence of minerals like iron and traces of plant matter. The salt has a unique flavor profile, with a slightly sulfurous, smoky taste that adds a savory depth to dishes. Black salt is often used in chaats, salads, chutneys, and in seasoning fruits like mango and cucumber. It’s also a key ingredient in many spice blends, such as chaat masala. Its distinctive taste can enhance curries, dals, and raita, making it a favorite in both vegetarian and non-vegetarian dishes. In addition to its culinary uses, black salt is known for its health benefits. It is believed to aid digestion, reduce bloating, and support detoxification. With its rich flavor and potential health benefits, black salt is a versatile addition to the spice rack.
