In a deep pan, heat the oil and add the cumin seeds. When they stop sizzling, add the onions and fry until soft and translucent, about 5 minutes.
Add the ginger and garlic and fry for 2 minutes.
Add the green chiles, tomatoes, coriander, cumin, garam masala, and turmeric, and fry until the oil separates from the masala, about 10 minutes.
Add the red kidney beans, warm water, and asafetida, as well as the salt to taste. Cook until the beans are soft, and the sauce has reduced a bit to your desired consistency, about 25 minutes.
Mash some of the beans roughly to thicken the sauce.
Garnish with cilantro and serve hot with rice and kachumber salad.
For an even better curry, cook kidney beans from dried instead of using canned beans. Soak the dried beans in water overnight and drain. Add the soaked beans to a pot, covering with about an inch of water. Bring to a low simmer and check after about an hour, adding more water as needed. The beans are done when they are tender.
For less intense heat, seed the chili peppers before chopping.
Serve with your choice of store-bought or homemade pickles.
