Add in the chicken with the marinade along with a half cup of water. Let it come to boil no high flame. Reduce heat to low and cook with lid on till chicken is done. It may take 20 minutes.
Meanwhile grind the dried red chilli and garlic cloves to a smooth paste. Keep aside.
After 20 minutes open the lid, if there is lots of gravy, increase heat and let te gravy get thick. Add in the ground masala along with half cup of water. Cook for another 10 minutes to remove the raw smell of the red chilli and garlic.
Add in coriander leaves. Check salt and add if needed.
Serve.
Notes
* Use Kashmiri dried chillies for grinding. The other type red chilli will be very very spicy.
