The egg whites are not evenly beaten. Egg white and milk must be beaten evenly, otherwise the egg white will agglomerate under steaming. In addition, steaming for too long sometimes leads to lumps. Generally speaking, you should beat the egg white before putting it down. After opening it, add it to the milk a little bit. If you beat it with an egg beater, you can add it all at once. In the case of steaming, you need to pay attention to it, as long as the surface layer is slightly solidified.
First, pour the milk into the pot and heat it. Just boil it (burning it for a long time will affect the protein and lose the milk skin), and then pour the milk into the prepared bowl. At this time, you can see a wrinkled milk skin on the surface of the milk. (If the milk skin is incomplete for a long time, it can be heated in the microwave oven for one to two minutes, and the milk skin will occur in detail.)
Prepare an empty bowl in advance, beat in two egg whites, add two spoonfuls of white sugar, and stir with an egg beater until the sugar melts completely. (Don't beat it for a long time, or it will turn into a bubble.) After the milk is a little cold, poke the milk skin with chopsticks, slowly pour the milk into the bowl with egg white, mix well, and then slowly pour it back to the bowl with milk skin along the edge of the bowl. This is because the milk skin will float by itself when you see it.
Finally, put the milk in a pot and steam it for ten minutes, and then insert it from the middle with chopsticks. If there is no milk discharged, it means that all the milk is solidified and the double-skin milk is made successfully. According to everyone's different taste, you can also add lotus seeds and small red beans to steam together, which is also rich in nutrition and top grade in beauty and skin care.
The raw materials of double-skin milk are raw eggs and egg whites, so we know that double-skin milk must also contain a lot of calcium and protein, which can bring nutrients to the body and enhance physical fitness. And the production process of double-skin milk is really very simple. Why don't you try it at home and put it in the refrigerator for refrigeration, which will taste better.
