To make rajma masala
In a thick-bottomed pot or dutch oven, heat oil (or ghee) on medium heat. Add the cumin seeds, asafoetida (thing), and bay leaves and cook until the seeds splutter.
Add in the onions and green chilli and saute till onions turn golden brown.
Stir in ginger and garlic paste. Saute till the garlic smell disappears.
Add the tomato puree and cook until the mixture reduces.
Mix in the tomato paste (optional and helps deepen the tomato flavor and color) and cook further until the masala thickens.
Add in the spices (turmeric, red chilli, coriander powder, garam masala) along with salt and pepper, and mix until well incorporated.
Cook until the masala starts oozing oil from the sides. That's the indication that bhuna masala is ready.
Add the cooked beans along with the water it was cooked in. Increase the heat to medium-high and bring this mixture to a boil and then simmer on low.
Using the back of your spoon or ladle, mash a few of the beans (in the pot itself). You can also use a potato masher. This helps to make the curry thick and smooth.
Crush some Kasuri methi between your palms and add to the curry along with cream (skip to keep it vegan). Mix well and simmer for another 10-15 mins stirring intermittently.
Finally, add some cilantro leaves, mix well. The gravy thickens as it sits so adjust consistency if required before serving.
Creamy, delicious Rajma masala is ready! Serve with hot zeera rice and enjoy Rajma chawal with some salad or sirkewala pyaaz (pickled onions).
