Chaat masala is a salty, tangy seasoning used in popular Indian snack foods. Sprinkling it on fruit and crudite also helps you eat healthy while adding a little kick to otherwise typical, humdrum fare.
Place a small frying pan over low heat and dry roast the coriander seeds until aromatic. Remove from the pan and dry-roast the cumin seeds, then separately, the ajowan.
Using a spice grinder or a pestle and mortar, grind the roasted mixture with the remaining ingredients to a fine powder.
Store in an airtight container.
