Description
Coriander-cumin seeds powder, as the name suggests is the ground form of the two seeds. Commonly, 
it is prepared by buying the whole seeds, toasting them slightly in a pan, and grinding in a mortal-pestle or electric grinder. However, it is also readily available in supermarkets. The powder tends to lose its flavour and aroma soon, so it is better to grind as and when needed.
Coriander-cumin seeds powder has a pleasant aroma and flavour that enhances many Indian dishes, especially vegetable preparations, savouries and snacks.
