How to make Xiancao milk tea with Xiancao powder in milk tea shop? Do you want to add sweet potato powder? How can it be frozen like jelly?

First of all, I worked as an old water bar in Xianlin Water Bar. Here, I will give you a brief introduction: first, boil the boiling water, put the Xiancao powder in the refrigerator and stir it evenly, and then put it in the quick-frozen refrigerator. Remember to freeze quickly, ordinary ones may not be easy to use. I think you just put it in the refrigerator. It is wrong to think that low temperature is enough. The refrigerator in our store is a Nestle freezer, which can be frozen in ten minutes. . . There should be no problem with your pace. The problem should be the refrigerator. Try another refrigerator. . . If not, there is no way out. Good luck!
