Taiwan Province rice balls can be cooked with rice cookers, and it is better to soak them. Because the rice in Taiwan Province rice balls is glutinous rice, which can be cooked by rice cookers, and the glutinous rice soaked in water tastes better and the rice balls are more fragrant and full. And we can soak Taiwan Province rice balls in cold water or hot water. If we soak them in cold water, the final taste will be better, but it takes a long time, which takes about eight hours. If rice balls are soaked in hot water, the preparation time can be shortened to one hour, but the taste is not as good as that soaked in cold water.

The above is my answer, I hope it can help you!
