Generally speaking, if you want to cool off the heat, cover the pot and cook the mung bean soup for 10 minutes, then turn off the heat. If you want to eat mung bean paste, you need to cook it for 30-60 minutes to make mung beans bloom.

You can use casserole or stainless steel pot to cook mung bean soup instead of iron pot, otherwise it will accelerate the destruction of polyphenols in mung beans.
