Taro ball (Chinese: 芋圓; Pe̍h-ōe-jī: ō͘-îⁿ) is a traditional Taiwanese dessert made of taro. It can be found in almost every part in Taiwan, among which Jiufen's taro ball is said to be the most famous. The taro balls can be made by mixing mashed taro with water and sweet potato flour or potato flour, making the taro balls more springy or softer respectively. The colour of mashed taro makes the dessert appear crystal purple or grey. The mashed taro can be replaced by mashed sweet potato or ground mung bean and becomes the yellow sweet potato ball (地瓜圓) or the green mung bean ball (綠豆圓).
