Lemuju, also known as ajwain seeds or carom seeds, is a small and aromatic spice used in many Asian and Middle Eastern dishes.

The seeds have a rough texture and a natural brown colour. The aroma smells intense, warm, and slightly minty. The flavour tastes sharp, bitter, and pepper-like.

Ajwain helps enhance the taste of bread, curry pastes, lentil dishes, and savoury snacks. Many people add it to fried foods because it gives a strong fragrance and aids digestion. The spice blends well with cumin, fennel, and coriander.
