Start by combining all the lentils in a large mixing bowl. Pour water and rinse the lentils by rubbing them between your fingertips. The water will become slightly dirty and cloudy.
Drain this water and repeat the process until the water is relatively clean. Rinse the lentils and drain. Set aside.
Start the Instant Pot in ‘SAUTE’ mode. Add ghee to the Instant Pot insert. Once the ghee is hot, add cumin seeds – cook the cumin seeds for a few seconds.
Add chopped ginger to the insert – cook for a minute.
Add diced onions to the Instant Pot insert. Sauté for 2-3 minutes. Add green chilies and diced tomatoes.
Stir in the dry spices – red chilies, turmeric powder, coriander powder, and salt to the insert.
Mix to combine. Sauté the spices for a minute.
Add rinsed panchmel lentils to the insert.
Pour in water. Mix until blended.
Seal the lid of the Instant Pot with the vent in the sealing position. Cancel the saute mode. Select the ‘PRESSURE COOK OR MANUAL’ mode. Cook on high pressure for 8 minutes.
Once the cooking time has elapsed, turn off the Instant Pot. Allow the pressure to release naturally. When the pin drops, carefully open the lid.
Pour water and adjust the consistency to your liking.
Press SAUTE mode again and simmer the dal for 4-5 minutes. As it starts to boil, turn the saute mode off.
