1, black tea is a little astringent. If it is too astringent, it is estimated that your tea is not good. Try Lipton. Don't put black tea until the water boils, and it will take too long to soak. You should put more cream (the cost of cream is not high, so you can put more cream and less other fruit powder to make people feel better) and less sugar. You have to master this yourself. Some of them. 4 yuan is enough. (If the tea is served after being chilled) 3 If it is boiled too much, the proportion of various raw materials can be well grasped. Just like cooking, there is no difference between frying a plate and frying a pot, and it will not become salty because of the increase in quantity. 4 small sales, you can cook by the cup. If you cook too much, you will find that cooking in a cup is no trouble at all. At the same time, it will give guests a fresh understanding of cooking. This is very useful. However, child soldiers are the most professional and can best reflect its value. 6 Juice is used to make freshly squeezed juice. Don't put it in at first, because some juice will react with some ingredients in milk powder, and the product is ugly. You can try it: apple juice is put in milk powder. That's it. Will the guests drink it after reading it? 7 Coffee and black tea are coffee+black tea+high concentration milk (usually three flowers and weak milk)+and sugar is decided by the guests. The longer the time, the richer the experience. The preparation work is: whether the pearls are fresh enough, whether the sugar, all kinds of milk powder are enough, whether the ice cubes and cups are enough, and whether the turnover is enough. The last thing to say is that all the formulas are not fixed. Be sure to ask the guest, even if he doesn't add it at first, and then he can take it back and redo it. The cost of this thing is very low, so don't be afraid of wasting it. I have been a bar for 4 years, and I know this thing better. I didn't find anyone else to write it ready. It's all my experience. If it is good, you can give it a small red flag.
