Take a large bowl, add 1 kg mutton in it along with 3 tbsp hung curd, 1 tbsp cumin powder, 2 tbsp ginger garlic paste, 1 tbsp chili powder, 1 tbsp coriander powder, and 1 1/2 tsp pink salt. Mix everything well and keep it aside to marinate for half an hour or 1 hour (or even longer).
Take a multi-instant cooking pot, add 1 tbsp ghee, and heat over low-medium flame. Add a small cinnamon stick, 6-7 peppercorns, 2 bay leaves, 2 cloves, 2-3 green cardamoms, and 2 black cardamoms to it.
Now, add marinated mutton to the pan. Keep stirring for 10 minutes till the oil separates from the mixture.
Make the Onion-Coriander Paste: Add 6 tbsp of deep-fried onions to a grinder, some garlic cloves, and coriander stems, and mix well. Further, add it to the cooking mutton in a pan. Close the pot and let it cook at the low-meat setting in a multi-instant pot.
Once it’s cooked, add salt to taste and garam masala and stir well.Serve it hot with rice, naan, or jeera rice.
