Mung beans: choose the small ones, not the big ones.
Stem rice: I use northeast fragrant rice, not too sticky.
Brown sugar: put a little brown sugar, it will have a sweet taste.
The ratio of mung bean to stem rice is about: 1 serving:1serving. There should be more water in the pressure cooker to avoid being too dry.
OK, cover the lid and let the pressure cooker cook for 15 minutes (I think it's been cooked long enough), and the mung bean porridge will be cooked.
