Marinate salt, turmeric, half of each ginger and garlic paste for 10 mins.
Heat oil. Brown the chicken pieces in medium heat. Remove and keep aside. In the same oil, add the onions, fry till golden brown. Add the remaining ginger garlic paste and the green chillies. Fry gently with the browned onions. Add the chicken pieces and stir all the ingredients for few mins. Pour hot water into the chicken mix. Simmer and cook the chicken till it is done. I usually do not use the lid for this dish and do slow cook.
Mix rice flour with one and half cup of water. Pour slowly on to the cooked chicken. Stir well and let it cook for five more mins. Remove and leave to sit for 15 mins. Garnish with coriander leaves .
