Take a pan, add roughly chopped onion, and chop tomato, garlic, ginger and 1 cup water, cook for few minutes, then blend all these with the blender to a smooth paste.
Return to the pan; add meat and red chilies & turmeric.
(Add an extra cup of water for mutton or veal.)
Let the water dry, add oil and fry and stir on medium heat till the meat is browned and oil separates from the gravy and sizzles on the spoon.
Add potatoes and water to make desired gravy.
Cook till potatoes are done and add green coriander.
