It is recommended to buy walnut powder, which is freshly ground. Steam walnuts in a microwave oven and grind them with a grinder. Add some fried sesame seeds and brown sugar. Pay attention to these two things. Because adding water will not be sticky, which is different from soybean milk and the like. There are also places selling freshly ground health powder in our supermarkets and downtown areas. Sesame does not cause obesity. Walnuts are rich in unsaturated fatty acids and vitamins. And freshly ground flour is cheaper and easier to absorb than buying ready-made walnuts. Of course, don't forget to rinse your mouth after eating. I wish you good health.
