To prepare this mutton recipe, start by washing the tomato, green chilli and onion under running water. Using a clean chopping board, chop up the tomato and green chilli, and slice up the onion. Next, put the chopped tomato and green chilli, and sliced onions, in a blender and blend it to form a smooth paste.
Now, in a large bowl, add curd along with Handi coriander powder, Handi garam masala powder, Handi red chilli powder, and Handi turmeric powder and mix them well. Then, add the mutton pieces to the bowl and toss it to evenly coat the mutton with the curd mixture. Let it marinate together for about an hour.
Next, take a pressure cooker over medium flame and heat oil in it. When the oil is hot enough, add the onion-tomato paste to the cooker and saute it till the raw aroma goes away. Then, add the achari masala and saute it for a minute before adding the marinated mutton pieces.
Cook for a couple of minutes, or till the curd loses its moisture. Then, add a cup of water and for seasoning. Mix everything and close the lid. Pressure cook this for 5-6 whistles.
When the dish is done, transfer it to a serving bowl and pair it with naan or lacha paratha. Garnish with a couple of coriander leaves and enjoy!
