Cumin (jeera) can be identified by its distinct ridged brown seeds and intense fragrance. Cumin is used to add a distinct smoky note and a robust flavour to most Indian curries. So, it is often used as a whole, to flavour rice, stuffed vegetables, curries and many savoury dishes, and as a powder for puddings and buttermilk.
Saffron (Kesar) is the most expensive spice and it is a colour too. Saffron has a very subtle flavour and aroma. It is used as a culinary seasoning for chicken and meat, biriyani, pulao, etc. It adds taste, colour, and aroma to Indian sweets like Rasmalai, Kesar Pista etc. and flavours kheer, badam milk, saffron milk, etc.
