Frozen jiaozi should be cooked in cold water. If you put hot water into the pot, the outer dumpling skin will become hot as soon as it is put into the pot. In addition, the frozen jiaozi has been cooked for a long time, so it is easy to see that the stuffing inside is not cooked and the dumpling skin outside is broken.

Frozen jiaozi, the fire should not be too big, otherwise the skin is ripe and the stuffing is not ripe. In addition, add a little salt to the water so that it won't stick to the skin. After the quick-frozen jiaozi is put into the pot, blanch it with a spatula to avoid sticking to the pot. Add cold water three times after the water is boiled, and add about half a bowl of cold water after each boiling. Most importantly, if jiaozi swells up, it will be ripe.

Boil the fresh jiaozi boiled water in a pot, and then put it in a jiaozi. When the water boils, add cold water and wait for the water to boil. Cook over low heat until the jiaozi swells. After the dumpling skin is shaped, cover it and cook the dumpling stuffing. Cover can reduce the loss of water vapor and heat, make dumpling stuffing easy to cook, and save time and fuel. At this time, the dumpling skin is mature and will not be broken by steam. Don't worry.
