Ajwain (Trachyspermum ammi) is also called king's cumin in Germany and belongs to the umbelliferae family (Apiaceae). The spice plant originally comes from the Mediterranean region and visually resembles celery seeds. The spice tastes aromatic to slightly bitter and is reminiscent of thyme. In India, the spice is used for potato dishes. However, the spice also goes perfectly with fish and in curry mixtures. In Ayurvedic medicine, ajwain is even used as a medicinal plant and is used to relieve abdominal pain and reduce fever.
