Generally, powder balls with larger particles are used to make tea, and the diameter after boiling is about 7 mm or more. If the diameter is too small, it is easy to swallow beads, but it is not convenient to swallow and chew. Before adding milk tea, rice balls are usually soaked in syrup to ensure that rice balls can remain sweet in sweet milk tea.
The base of milk tea is usually black tea, but some stores also provide bubble tea with green tea (called pearl green milk or pearl milk green). There are also many shops that add coffee jelly, tofu, pudding, grass and other similar foods to milk tea, so that guests can choose freely to add flavor.
