Black salt, or 'kala namak', in North Indian cuisine provides a distinctive sulfurous, pungent flavor that enhances chaats and drinks, adding a savory and slightly tangy dimension. It also aids digestion.
Black salt, unlike regular table salt, is a volcanic rock salt that contains sodium chloride along with other minerals like iron sulfide, magnesium, and sulfates. These minerals contribute to its unique flavor profile, which is often described as sulfurous, eggy, and pungent. In North Indian cuisine, particularly in dishes like chaats (such as aloo tikki, pani puri, and bhel puri), black salt is used to add a complex savory flavor that complements the other sweet, sour, and spicy elements. It also enhances the overall taste experience by providing a subtle umami note.
Furthermore, black salt is believed to have digestive properties in Ayurveda. It is often added to drinks like jal jeera and chaas (buttermilk) to aid digestion and reduce bloating. The sulfur compounds in black salt are thought to stimulate the production of digestive enzymes, making it a popular ingredient in these beverages. The distinct flavor also makes these drinks more refreshing and palatable.
When using black salt, start with a small amount and adjust to taste. Its strong flavor can easily overpower a dish if used excessively.
