About Black Salt (Kala Namak)

The traditional process involves sealing Himalayan rock salt in ceramic jars with charcoal, harad seeds, amla, and other herbs, then firing in a kiln for 24 hours. The high heat triggers a chemical reaction that produces sulfur compounds, giving the salt its distinctive flavor and color.
Best for: Vegan egg dishes (tofu scramble), Indian chaat, Raita, Chutneys, Fruit salads with chaat masala.
