Actually, it's not hard to imagine that there are three reasons for jiaozi's broken skin: 1. Jiaozi sticks to the bottom of the pot; 2. It is related to 1. In order to prevent sticking to the pot, push the dumpling skin with a spatula or spoon and break it. 3. Because the water in the pot boiled, the water in the pot stirred violently, which led to the violent movement of jiaozi, which led to the violent collision of jiaozi and the skin of jiaozi was broken.
Knowing the reason of jiaozi's broken skin, the problem is not difficult to solve. The reason why the dumpling skin sticks to the pot is that the dumpling skin becomes sticky as soon as it touches water. Therefore, it is necessary to heat the water until it boils, and then cook the jiaozi, so that the dumpling skin can be hardened as soon as possible and the viscosity can be reduced. Moreover, the water rises quickly, effectively reducing the direct contact between jiaozi and the bottom of the pot. After jiaozi sinks to the bottom, push it with a spatula or spoon in time, but gently, and push the spatula or spoon in turn. This not only reduced the pressure on jiaozi, but also increased the contact area with jiaozi, effectively reduced the pressure on jiaozi and prevented jiaozi from being pushed. In order to prevent the dumplings from strenuous exercise, after the dumplings are boiled again in the pot, appropriate amount of cold water should be poured in time, and the pot cover should be covered for heating. Adding cold water only makes the temperature of the water in the pot slightly lower than the boiling point, that is, it stops boiling, but the temperature is still very high, so that jiaozi can absorb heat in relatively stable water, and jiaozi will not be broken by collision. Cover the lid to prevent water vapor from escaping, which can increase the air pressure, make the boiling point of water rise, and make jiaozi absorb heat faster.
