Coriander Seeds (Dhania Whole Indori) possibly the most important of all curry ingredients. Coriander seeds have a warm fragrant odour and pleasant, mild taste.Perhaps one of the hardest seeds to find fresh because it doesn't change in appearance much over time. The best indicator of quality is to grind a small amount and smell. You should get a strong, almost overpowering lemon smell. Used as the main ingredient in curries, it's seen everywhere in Middle-Eastern and Indian cuisine. A popular spice used in most Indian dishes.
