Method
Grill whole tomatoes over gas flame or under electric griller until skins wrinkle. Peel and chop. Heat ghee or oil in a saucepan or karahi and fry the onion and ginger until golden. Add tomatoes and remaining ingredients. Cover and cook until the tomatoes are a thick pulp and most of the liquid evaporates. Serve with rice or chapatis.
