To make plain soymilk with the SoyaJoy soymilk machine , you do not need any more than the instructions in the User's Manual . To make soymilk with your favorite flavor, just add that flavor after the soymilk is made. I usually add sugar. Do not feel guilty about adding sugar because most likely you have added less than what is in commercial soymilk or most other drinks. You can also use sugar alternatives.
Some people like to add a little salt.
Vanilla flavor is also a favorite and known to cover the bean taste pretty well. Some customers have reported that blending cold soymilk with banana is great. Many customers reported that their home made soymilk taste better than the expensive commercial soy milk such as Eden soy, SoyDream, white wave silk, etc. We will post it here. We have had our SoyaJoy soymilk maker for about six months now.
