When the pressure settles down on its own, open the lid of the pressure cooker.
Then add the ginger-garlic paste, tomato puree, Kashmiri red chili powder, butter, cream and salt. Also add 1 to 1.5 cups of water.
Stir very well and keep the pressure cooker on low heat, without its lid on. Let the dal simmer for about 1 hour or 1 hour 30 minutes.
Keep stirring often, so that the lentils don't stick at the bottom of the cooker. Also mash some of the lentils while stirring.
If the dal becomes thick, then add some hot water. Once done, check the taste and add more red chili powder or salt if required.
Lastly sprinkle garam masala powder and stir well.
While serving Dal Bukhara, dot with butter or cream. Garnish with ginger juliennes (optional).
Serve hot with jeera rice or with Indian flatbreads like naan, paratha or roti.
