1, quick-frozen jiaozi is frozen for too long, so the water in the dumpling wrapper will evaporate, and jiaozi is not easy to cook, and it will be a little raw. It is not suitable for cooking with large fire. Cook jiaozi slowly over low heat.

2. Boil more water and add some salt in jiaozi to increase the boiling resistance of dumpling wrappers.

3. Boil the water, then put jiaozi into the pot, and fully stir it from time to time to prevent jiaozi from sticking to the pot.

4. Don't let the water boil too much, or the jiaozi will break easily. Add a little cold water after the water boils, and then add cold water after the water boils. Repeat this action three times.

5. Boil and freeze jiaozi. Observe the shape of jiaozi. jiaozi will soften slowly after cooking. If jiaozi floats on the water and the dumpling skin is uneven, it means that jiaozi is ripe.
