Sure! I tried. Nutritionists suggest that we should eat more than five colors every day. This is a good match! It is recommended to add some glutinous rice, because porridge tastes sticky.
There are also black rice and corn kernels in the supermarket!
My grandma likes the porridge I cooked for her!
Oh, I also need to buy dozens of clay pots specially used for cooking porridge. Turn them down when the water boils, which will save gas!
