Black beans, also known as black beans and black beans, are sweet and flat. Black beans are a kind of soybean, which is rich in protein, fat, carbohydrate and carotene, vitamin B1, B2, folic acid, folinic acid, riboflavin, vitamin A and carotenoids, niacin and crude fiber, calcium, Phosphorus, iron and other nutrients. I went to Hokkaido for the first time to eat black bean yoghurt and even ate three bowls. I like it very much~ I have to do it myself. You can cook more at a time and put a sealed box to eat at any time.
Black beans with appropriate amount of water and rock sugar electric cooker or rice cooker boiled softly with cold yogurt.
Soaking for 2-3 hours in advance will be easier to cook.
