Heat oil in a pressure cooker/pan and add chopped onions and sauté till light brown. Then add ginger-garlic paste and sauté again for another minute. Next add red chilli powder, coriander powder, jeera powder and mustard seed powder and sauté again for 30 seconds.

Add the chicken pieces and salt and sear on high flame for 5 minutes. Reduce heat and add tomato puree and cook again for 5 minutes.

Next add the vinegar and cook the chicken till juicy and tender. No extra water is added as water gets released while pressure cooking. But if you are using the pot method, then you may need to add a little water for cooking the chicken pieces.

Serve hot with rice, rotis or bread.
