Ajwain (Trachyspermum Ammi) is a plant that produces small, seed-like fruits similar to caraway and cumin. It comes from the Apiaceae family, which is a group of plants that includes celery, caraway, coriander, fennel, parsley, and parsnips. It goes by many other names, including carom seed, bishop’s weed, and ajowan caraway. Ajwain is common in Indian food. It has a strong, bitter taste with an aroma similar to thyme. The “seeds,” which are actually fruits, are typically dry-roasted or ground and used in spice mixtures.
