  • 500 grams lamb or mutton cut into chunks on the bone
  • For the Marinade:
  • 3 tsp curd
  • 2 tsp tomato puree
  • 2 tsp each of Kashmiri chilli powder can be substituted with paprika powder, garam masala powder, cumin (jeera) powder
  • 1/2 tsp turmeric powder haldi
  • 1 tsp salt
  • For the spiced masala:
  • 2 tsp vegetable oil Mustard oil is the best option
  • Whole spices - 4 cardamom 1 small stick cinnamon, 4 cloves, 2-3 bay leaves
  • 3 onions ground to paste
  • 2 tbsp of ginger paste
  • 1 tbsp of garlic paste
  • Pulp of 2 tomatoes - I blended 2 blanched tomatoes in my blender
  • 3 potatoes cut into 1" cubes
  • 1 tsp sugar
  • 1 tsp chopped coriander leaves


  • Marinate the lamb (or mutton) with all the ingredients listed under 'marinade' keep this for at least 1 hour, or overnight
  • If using a pressure cooker, turn on the heat and add oil in it
  • Saute the whole spices and bay leaves in the heated oil
  • Once the spices crackle, add the onion paste
  • Keep stirring until the onion paste is light brown (Kalyan stresses on this point, the onion paste has to be browned before the next step)
  • If the mixture sticks to the base, add half a cup water and stir
  • Add the ginger and garlic paste and stir the mixture
  • Add the tomato pulp and continue stirring
  • At this stage, add the marinated lamb along with the potato, chopped coriander leaves, sugar and stir the mixture together for about 5 minutes.
  • Pressure cook the lamb in the spices (there is no need to add water) for 10 minutes and let the steam release naturally
  • Once the pressure cooker is opened, saute for a few minutes until any residual water is evaporated
  • Serve with flatbread of your choice


I used an electric pressure cooker, which cooks at a lower pressure than a stove-top pressure cooker. If using a stove-top pressure cooker, add another 1/2 cup water and cook for 4-5 whistles
