On a thick bottom pan dry roast ingredients one at a time on low-medium heat till you can smell their aroma and coriander seeds start to turn brown. Stir almost constantly. (3-5 minutes)
Cool this mix and grind with the other ingredients. Adjust the spice(chili), and sour(pomegranate seeds and rock salt) to taste. We add a bit more spice and mom adds another teaspoon of dry mango powder for a more sour masala blend.
