material
Two servings of glutinous rice, one serving of millet, one serving of mung bean (the kind with skin but split in two, which is easy to boil and soften) and one serving of corn (which is available in most Asian supermarkets). The dried corn was crushed, so it cooked well.
working methods
Put all the ingredients in a saucepan, add boiling water and stew overnight. I usually cook porridge before going to bed at night, and I have delicious porridge to drink the next morning.
