Rub the mixture of raw papaya, ginger garlic paste and salt on mutton leg and leave for 40-45 min and set aside.
In a bowl add yogurt and all spice and mix well. Pour the marinating over the leg and rub it over well and leave for another 2-3 hours.
Place the leg in a large pan with oil (1/3 cup) and water (1 cup) in bottom and leave on very low flame for 2 hours almost. Keep flipping the sides so leg and masala shouldn’t get burnt.
Or Place the leg on greased baking tray, cover with foil and bake at 170 C for 1 ½ to 2 hours (may take ½ hour more) or till meat is fully done.
Serve Hot.
