Close to a year back, I had some super yummy Rajma cooked by a dear friend at a farewell dinner. Try this and tell me if you agree...
Rajma 1 katori, soaked overnight, boiled with pinch of turmeric. Rajma being hard beans need at least 30 mins pressure
Onion 2 large , first boil them in water n then purée them
Tomatoes 3 large, first boil them in water then purée them
Garlic n ginger paste
Green chilli 2 if less spicy variants! You can purée this with the onion
Pepper corns 3
Cinnamon 1/2 inch piece
Jeera 1/2 tsp
Garam masala powder 1/2 tsp
Coriander leaves finely chopped
Take 2 tbsps oil, add jeera, whole Garam masala (in this case 3 ing specified earlier), fry lightly till aromatic, add ginger garlic paste, green chilli+ onion purée, once it has reddened, then add tomato purée, garam masala powder 1/2 tsp, when the masala leaves oil, add Rajma, simmer for 10 mins, and finally add finely chopped coriander to garnish.
Tastes yummy with Garam Garam phulkas.
