Black Salt / काला नमक / Kala Namak

Uses

Powdered kala namak
Kala namak is used extensively in South Asian cuisines of Bangladesh, Nepal, India and Pakistan as a condiment or added to chaats, chutneys, salads, all kinds of fruits, raitas and many other savory Indian snacks. Chaat masala, an Indian spice blend, is dependent upon black salt for its characteristic sulfurous hard-boiled-egg aroma. Those who are not accustomed to black salt often describe the smell as similar to rotten eggs. Kala namak is appreciated by some vegans in dishes that mimic the taste of eggs. It is used, for example, to season tofu or avocado to mimic an egg salad[citation needed] or deviled eggs.

Kala namak is considered a cooling spice in Ayurveda and is used as a laxative and digestive aid. It is also believed to relieve flatulence and heartburn. It is used in Jammu to cure goitres.[ This salt is also used to treat hysteria and for making toothpastes by combining it with other mineral and plant ingredients.
