Marinate mutton pieces with turmeric powder, salt, ginger-garlic paste, and lemon juice for 30 minutes.
Add Kashmiri chili powder and Malvani masala powder to the marinated mutton and mix well.
Heat oil in a pressure cooker and sauté sliced onions, garlic cloves, ginger, and dry coconut until golden brown.
Add chopped tomatoes and cook until they become mushy and soft.
Add the marinated mutton, green chilies, coriander leaves, and water to the pressure cooker.
Pressure cook for approximately 2 whistles or until the mutton becomes tender.
Once pressure releases naturally, stir the curry and adjust seasoning before serving hot.
