Ajwain (also known as carom sees or bishop's weed), is an uncommon spice except in certain areas of Asia. It is the small seed-like fruit of the Bishop's Weed plant, (Trachyspermum ammi syn. Carum copticum), egg-shaped and grayish in colour. The plant has a similarity to parsley. Because of their seed-like appearance, the fruit pods are sometimes called ajwain seeds or bishop's weed seeds.
