I used glutinous rice flour (white), sweet potato (yellow) and purple potato (purple) together with glutinous rice. Please refer to the specific operation method: http://www.meishij.net/zuofa/muguasansetangyuan.html
I have prepared the Yuanzi and put it in the refrigerator to freeze it, and then take it out when needed.
2. After the water in the pot is boiled, put the Yuanzi in and stir it with a spoon to prevent the Yuanzi from sticking to the pan
3. After boiling until the water boils, add a small amount of cold water to let it no longer boil.
4. Continue to boil until the water boils, so two to three times
5. Cook until the glutinous rice balls are raised and the glutinous rice balls become bigger obviously, add appropriate amount of sugar.
6. Serve and eat.
After the glutinous rice balls are frozen from the refrigerator, they must be cooked thoroughly. Otherwise, it will hurt your stomach.
