Wash rajma and soak them overnight in water (around 6-8 hours). Do not throw away the water as it can later be used in the gravy.
1.5 Cups Rajma (Red Kidney Beans)
Heat oil in a pressure cooker and add cumin seeds. I prepare the masala directly in the pressure cooker and add the rajma to it later to boil so that the rajma absorbs the masala while cooking. You can also boil the rajma separately and add the masala to it later.
1 Teaspoon Cumin Seeds (Jeera)
When the cumin seeds have roasted, add minced garlic, finely chopped ginger and finely chopped green chillies.
5-6 Garlic Cloves, 1 Inch Piece of Ginger, 2 Green Chillies
Add finely chopped onions and fry them till they become soft and golden brown or translucent.
2 Medium Sized Onions
Add 2-3 pureed tomatoes and cook for a few minutes.
2-3 Tomatoes
Then add haldi (turmeric powder), garam masala, coriander powder, rajma masala, red chilli powder, salt and a pinch of heeng (asafoetida) and roast properly.
1/4 Teaspoon Heeng (Asafoetida), 1/2 Teaspoon Turmeric Powder (Haldi), 3/4 Teaspoon Garam Masala, 2.5 Teaspoons Rajma Masala, 1 Teaspoon Red Chilli Powder, 2-3 Teaspoons Salt, 1.5 Teaspoon Coriander Powder (Dhaniya Powder)
When the masala has cooked, add 4 cups of water along with the rajma. You can use the water in which the rajma was soaked to get a richer color and texture.
Close the lid of the pressure cooker and cook till 2 whistles. The gravy should be of a thick consistency by now. If it's still watery boil for a few more minutes. You can crush some of the kidney beans with the back of the spoon to make the gravy thicker.
