Step 1: Rinse the mung beans with cold water and drain well.
Step 2: Put mung beans in a large pot and add the water. Bring to a boil over high heat, then reduce to medium-low and cook for 1 hour.
Step 3: While mung beans are cooking, melt the coconut oil in a small frying pan over medium heat; add ginger and sauté about 1 minute, stirring often. Add cumin seeds, cover, and cook until you hear the seeds popping, then stir in curry powder, turmeric powder, and asafetida. Cook 1 more minute, set aside.
Step 4: When the mung beans are fully cooked and soft, transfer them to a food processor, stir in coconut milk, salt, and red pepper, and blend until smooth and creamy.
Step 5: Pour the blended mixture back into the large pot, add the cooked spices and curry leaves, and stir well. Continue cooking for another 5 minutes.
Step 6: Serve in bowls garnished with 1 tablespoon of chopped cilantro.
