Generally, if you buy double-skin milk, there will be a ratio of powder to water in the powder bag. For example, the ratio shown on the powder I bought is 1:8, powder 1, and water 8. But today, I feel that this ratio is not very good in taste, because although double-skin milk is condensed milk, it spreads like tofu in the mouth, feeling like water in the mouth, and personally feeling like a lump.
