In the preparation of chicken handi here, I am pre cooking the chicken to make it well cooked and to easliy blend with the spices. In a  pan we fry onion paste till oil separates. Later add finely chopped tomatoes, till oil separates. Later add chicken pieces. Once cooked, then add fried onions and spice powders. Next add curd to cook niecly. Now we add mince ginger and split green chillies. Once all cooked well, add little water and cook further. Finally add malai (cream) and stir well. That's it.
