Soybeans must be added to the whole grain soybean milk. There is a small measuring cup attached to the box, as long as it does not exceed its measurement. The so-called rice paste is made of rice only, without adding soybeans. Whether it is rice paste or soybean milk, it is best to soak the raw materials before beating them, so that they are delicious. What has not been soaked has a strange smell, and it is not easy to hurt the machine if it is soaked. The amount of water added is: there are two horizontal lines in the machine cup, namely the minimum water amount and the maximum water amount. Just add these two lines. If there are many people, add it to the highest water level. (It can't be any higher, otherwise it won't work.) If there are few people, add it to the lowest water level, both of us, but both of us can drink the highest water level.
