The ultimate comfort food from mum's kitchen -not sure if there is any fancy name for this but in Bihar it's called 'Godla'
So this is what you need:
Kala chana (Black gram) - 1 cup
Potato -1 medium size
Onion - 2 medium
Garlic -4/5 pods
Cumin powder -1 tea spoon
Coriander powder - 1 tea spoon
Turmeric powder -1/3 teaspoon
Garam masala powder - 1/2 teaspoon
Bay leaves -2 /3
Badi elachi (Black cardamom )- 1
Red chillies -2/3 depending on taste ( I also remove the seeds to reduce heat and still get that slightly smokey flavour)
Ghee (Clarified butter or any other cooking oil) - 1 generous tablespoon
Salt - to taste
Soak kala chana for at least 4-5 hours
Grind it into a coarse paste - try not to make a too fine paste, this is a rustic dish, all the different texture of chana adds to the flavour
Chop up 1 1/2 onion finely
Use remaining half onion, ginger and garlic and make a rough paste.
Now heat ghee in a pressure cooker, add bay leaves, black cardamom and red chilli, sauté for half a minute
Add the onion, garlic and ginger mix , sauté for further 2 mins , add the chopped onion , turn down the heat to low and let the onion sweat completely , mixing this masala every couple of minutes.
After about 8-10 mins when the onion becomes all soggy , add cumin, coriander and turmeric powder , keep the heat low and sauté for further five mins.
Into this mix add the kala chana mix, sauté for again 10- 15 mins, you don't have to mix constantly just every couple of mins, ensure the heat is at the lowest level so it doesn't burn or sticks.
Cut potato into 4/6 piece add it into the pressure cooker , mix well.
Add salt, garam masala powder and 3-4 cups of water.
Cover and cook on medium heat for 3-4 whistle.
