1. When cooking glutinous rice balls, be sure to boil the water before adding the glutinous rice balls. After adding the glutinous rice balls, use high heat to keep the water in the pot rolling vigorously so that the glutinous rice balls can be heated evenly.

2. When the water boils, put the glutinous rice balls into the pot and gently push them in one direction with a spoon to try to make the glutinous rice balls rotate and prevent them from sticking together.

3. When the water in the pot boils again, reduce the heat to low and add an appropriate amount of cold water. In this way, the glutinous rice balls will not be cooked due to uneven heating.

4. Add a small amount of cold water each time the water boils and repeat three times. Add cold water for the last time and cook the glutinous rice balls for a while before they are ready.
