2. Brewing steps of whole grain flour: pour boiling water at about 80 degrees Celsius into the cup to two-thirds of the mouth of the cup. If it is too full, it will overflow easily.

Generally, we only need to add 3-4 spoonfuls of whole grain flour, which can make the distribution of nutrients more coordinated and more suitable for soaking whole grains in the shade. At the same time, according to personal preferences, you can add your favorite rock sugar, honey and so on. As an auxiliary material, the taste is more abundant. After the mixing is completed, a cup of nutritious and delicate cereal powder is ready.
