Stovetop kala chana in cooker
Heat oil in a pressure cooker. Then add cumin seeds.
When they sizzle, add onions and saute until they turn light golden.
Next add ginger garlic and saute for a minute or until a nice aroma comes out.
Add tomato puree and cook for a while until it turns thick.
Next stir in the spice powders - turmeric, red chilli powder, garam masala, coriander powder and salt. Saute well until the mixture smells good and begins to leave the sides of the pan.
Pour 3 cups water and add the drained kala chana. Stir well and cover the pressure cooker with the lid.
Pressure cook on a medium flame for 10 whistles. Let the pressure release naturally.
Open the lid and check if the kala chana is tender & cooked. If not pressure cook for 2 more whistles.
Then add coriander leaves and all the other optional ingredients - ginger juliennes, ghee and crushed kasuri methi. Simmer for 2 to 3 minutes. Taste test and add more salt if needed. Serve kala chana with rice or roti.
Stovetop black chickpeas in pot
Soak them overnight. Drain and cook with 3 cups of water. Keep adding more water as they cook. They will take about 1 hour 30 mins to cook tender. Then add them to the onion tomato masala & simmer for 15 to 20 mins so they absorb the flavors.
Instant pot kala chana
Press saute button. When the IP displays hot, pour oil to the inner pot of the IP.
Add cumin and let them sizzle. Stir in the onions and salt. Saute until they turn light golden.
Saute ginger garlic for 30 seconds. Add tomatoes, salt and all the spice powders. Saute until the mix turns slightly thick and aromatic for 2 mins.
Pour 2 cups water and deglaze the pot by scrubbing the bottom with a wooden spatula. This releases any bits of food stuck & prevents a burn sign.
Then add the drained kala chana and give a good stir. Press CANCEL button.
Secure the IP with lid and position the steam release handle to sealing.
Press PRESSURE COOK button (high) and set the timer to 35 to 40 mins. Or you can also use the bean chilli mode and set the timer to 40 mins.
When the IP is done cooking, it will beep. Allow the pressure to release naturally for atleast 15 mins.
This step is optional - Add some ghee, kasuri methi and ginger juliennes. Mix well and cook on saute mode for 2 minutes. Garnish kala chana with coriander leaves. Sprinkle some lemon juice and serve with rice or roti.
