1. There is too much water. When steaming eggs, drain the water properly. Generally, the ratio of water to eggs is about 1: 1. If you put too much water, the eggs will become thinner, the surface of the steamed eggs will be older and there will be excess water at the bottom.
2. There is not enough steaming time. The time for steaming eggs needs to be properly controlled. If the time is too short, the eggs will be immature, the surface will be old and there will be water at the bottom. Generally speaking, it takes 10- 15 minutes to steam eggs on medium heat.
3. The temperature is not enough. If the heat is not enough, the eggs will not be cooked, the surface will be old and there will be water at the bottom. Therefore, when steaming eggs, it is necessary to properly improve the heat.
To sum up, the reason why steamed eggs have old surfaces and water at the bottom may be that too much water is put in, the steaming time is not enough or the heat is not enough. To solve this problem, we can reduce the amount of water, appropriately extend the steaming time or increase the heat. As for whether the egg is mature, it needs to be judged according to the specific situation. If you are not sure whether the egg is cooked, you can gently poke the yolk with chopsticks. If the yolk is solidified, it means that the egg is ripe.
