In a skillet, dry roast the cumin seeds, coriander seeds, ajwain, black peppercorns, and button red chillies over low heat, stirring and shaking the skillet often, until aromatic and golden brown.
Remove from heat and allow the mixture to cool completely.
Grind the roasted spices into a fine powder using a spice grinder or mortar and pestle.
Add the remaining ingredients and grind again to mix thoroughly.
Your homemade chaat masala is ready!
