Black Salt: Black Salt, or Kala Namak is usually found at a Desi market or a good pan-Asian market that features ingredients popular in Indian and other South Asian cuisines. It is mostly sodium chloride, but it also contains sulfur in addition to the other minerals. It is pink or light purple in color and imparts a more subtle flavor cooked. It can be skipped, just add ¼ t of sea salt, but it worth the effort to seek it out. If you don’t have any suitable markets in your area, Kala Namak Salt can be purchased online.
