To a heavy bottomed kadai add 1 cup whole urad dal(without skin) and 6 tablespoon, chana dal.
Add 20-25 red chillies. Either use half and half of regular red chillies or use kashmiri chillies iteslf. I used 20 kashmiri red chillies. Adding red chillies along with dal while roasting helps in avoiding burning of red chillies.
Dry roast it slowly in low flame. Keep stirring without burning.
Roast until dals turn golden brown and red chillies turn crisp. Transfer to the same plate and set aside.
Heat 1/2 teaspoon oil then add 15 nos small sized garlic(with skin).
Roast until golden. Transfer to the same plate and set aside.

Roast until crisp. Transfer to the same plate and set aside.
Now add 1 tablespoon sesame seeds.
Roast until golden and let it pop. Transfer to the same plate and set aside.
Finally add rock salt.
Dry roast for few seconds. Transfer to the same plate and set aside.
Cool down the ingredients completely.
Transfer to a dry mixer jar.

Spread it on a plate and cool down.
Store in a dry jar and use it.
Serve Idli Podi with hot idlis / dosa and enjoy!
