Marinade the mutton with everything and keep it aside for 2 hours. You can keep it in the fridge for the marination time.
In the cooker on low flame, melt the ghee. Add the whole spices until they leave aroma.
Add onion and stir till it turns translucent. Add the ginger garlic paste and cook for 2-3 minutes
Add the marinated mutton and roast for 5 minutes untill mutton changes colour
Add the garam masala, cumin and coriander powder. Mix and cook for 5 minutes.
Add the tomato pulp ( I just cut 2 small tomatoes in the grinder and made pulp) and mix well. Cook for 5 minutes. Keep turning.
Add water and stir well. Close the lid of the cooker and give 6-7 whistles. Switch off the flame. Rest it as it is for 10 minutes. Let all the steam escape , lift the whistle up to do that. Garnish with Coriander.
You can serve it with Keto Naan or have as it is. Make sure you squeeze some lemon before having it, adds to the taste more.
