To begin making�Dum Pukht Gosht we will first prepare the ingredients required for marinating the mutton.�Heat ghee in a preheated pan; add the onions and saute until the onion turn golden brown.Once the onions have started to turn golden brown add all the whole spices, black cardamom, green cardamom, cloves, cinnamon stick, peppercorn and saute till the spices release a nice aroma. Turn off the heat and let it cool.Once cooled add the caramelized onions and the whole spices to a mixer grinder. Add the garlic, ginger, green chillies and half the curd and grind to a smooth paste.�Marinate the mutton with the above ground spice curd and onion mixture.�Add the remaining curd, chilli powder, turmeric powder, coriander powder,garam masala powder, salt to taste to the above mutton and marinate it in the refrigerator for two hours or overnight.You can marinate the meat longer to get maximum flavour in the dish.�While the mutton is marinating knead the dough that you need to seal the vessel in which you are going to cook the gosht in. The dough should be a bit stiff, like how you knead for puris.*To make the�Dum Pukht GoshtOnce the mutton has marinated, preheat a heavy bottomed vessel or handi and add some ghee.Add the marinated mutton in the handi and saute for a few minutes till the marinated mutton leaves oil on the sides. This will take about 10 minutes. Add one glass of water and bring the Mutton gosht to a boil.Cover the handi with a lid and seal it with the wheat dough and leave the Mutton�gosht cook on low heat for about 50 minutes. This process of covering and sealing the lid with the dough is called "Dum Cooking" - a very slow cooking process that brings in flavours to the dish.After about one hour turn off the heat and remove the dough on the lid with the help of a kitchen knife.You will notice the�Dum Pukht Gosht has a rich colour and taste with all the natural oils from the the mutton released into the dish. Give it a stir and adjust the salt accordingly.�Transfer the Dum Pukht Gosht into a serving dish and garnish with coriander leaves and serve hot.Serve Dum Pukht Gosht with hot with�Mande Roti�or�Butter Garlic Naan�and�Tomato Onion Cucumber Raita�for a weekend lunch or dinner. you can even serve it at your next dinner party.
