Run your washed and drained mince in a mixer/blender so that it becomes pasty. Mix this throughly with the chopped ginger, garlic, chillis, 2-3 tbsp coriander leaves, 1 tsp garam masala and a tsp of salt
Pinch out golf ball sized portion of the mince mixture and make smooth balls out of them. Refrigerate, until needed
Heat the mustard oil until it smokes, lower the flame to medium and add the cinnamon, cardamoms, cloves, cumin seeds and bay leaves. When they turn fragrant, add the ginger and garlic paste
Cook for a couple minutes and then add the tomatoes, turmeric powder, coriander powder, cumin powder and chili powder. Mix well and cook over medium flame until the oil separates
Then, lower the flame and add the fried onions, yoghurt and cashew paste. Mix well and cook until the oil separates
Add a cup of water, the remaining coriander leaves and garam masala and let this curry come to a simmer
When simmering, remove the meatballs from your refrigerator and gently drop them in the simmering curry, along with salt to taste and the nutmeg powder. Cover and cook over medium heat for 20-25 minutes, stirring gently in 10 minutes intervals. Switch the flame off and let it sit for 5 minutes before serving
Garnish your delicious mutton (lamb) kofta curry with some more coriander leaves and as a side dish along with naan and/or pulaos. Enjoy!
