Rajma Gravy Place the kidney beans into a large container and cover with several inches of cool water; let stand 8 hours or overnight. Drain and rinse. Grind the onion, ginger, and garlic into a paste using a mortar and pestle. Heat the oil and ghee together in a pressure cooker over medium heat. Fry the red chile peppers, cumin seeds, and whole cloves in the hot oil until the cumin seeds begin to splutter; stir the onion paste into the mixture and cook, stirring frequently, until golden brown. Season with the ground turmeric, ground cumin, and ground coriander; continue cooking for a few more seconds before adding the tomatoes. Cook until the tomatoes are completely tender.
