Bubble tea, also known as Boba milk tea, or Jane milk for short, is a kind of tea beverage that spreads in Taiwan Province Province. After milk tea is added to the rice ball, it becomes bubble tea. Because of its special taste, it is very popular with teenagers. Generally, powder balls with larger particles are used to make tea, and the diameter after boiling is about 7 mm or more. Otherwise, if the diameter is too small, it is easy to swallow beads, and it is not convenient to swallow and chew. But most tea makers still provide small round pearls. Of course, there is also a kind of amber pearl, which is made of 100% brown sugar.
