The best way to cook mung beans is in a pressure cooker. Here are 3 ways to cook mung beans: 1. (Most recommended) Soak them in water for 4-5 hours and then cook either in a pressure cooker or boil them in a saucepan/rice pot with plenty of water till they are cooked through, but not mushy. Add salt while cooking.  2. If you have forgotten to soak the beans ahead, do not worry! Soak them in hot water for 1 hour (with the lid on) and then cook them as mentioned above. 3. (Least recommended) Cooking mung beans without soaking them ahead of time: bring water to boil (the quantity of water should be 3 times that of mung beans). Add the beans and salt. Bring the water to a boil again. Reduce heat, cover, and cook on low heat for 25-30 minutes or until the beans are soft (stir and check on them a couple of times).
