Quick-frozen glutinous rice balls need to be taken out of the refrigerator and defrosted before steaming, otherwise it will prolong the steaming time. Wait until they are almost thawed before steaming them, but be sure to wait until the water boils before putting them in. Put it into the pot so that the steamed glutinous rice balls will be more plump. After the water for steaming the glutinous rice balls boils, steam them for about 10 minutes before they are ready.

Tip: When steaming glutinous rice balls, be sure to wait until the water in the steamer boils before adding the glutinous rice balls, so that the steamed glutinous rice balls will have a fuller shape.
