Soak both the dal and boil them. Keep aside. In a kadhai add refined oil and as it heats up add the whole garam masalas. Let them crackle add the onions, fry them till red. Add the tomatoes, let them melt, add the ginger garlic paste. Cook.

Add the turmeric powder, salt and mix them well. Add the dry powders- cumin, coriander and black pepper. Add the leftover mutton.

Cook well and cover till the mash of the two is perfect. Serve hot with roti.
