When cooking jiaozi, be sure to boil the water first, then put it in, and then cook it with strong fire to keep the water in the pot tumbling strongly, so that jiaozi won't stick to the bottom of the pot.
It should be noted that when the water is boiling, after jiaozi is put into the pot, it should be gently pushed in one direction with a spoon, and the jiaozi should be rotated as much as possible to prevent sticking together and not easily sticking to the bottom of the pot; Jiaozi floats, so you don't have to push.
When the water in the pot boils again, turn the heat down and add some cold water. In this way, jiaozi won't be stuffed or undercooked due to uneven heating. Add a small amount of cold water after each boiling, and repeat for three times. After adding cold water for the last time, cook jiaozi for a while, and then you can go out.
Finally, you can sprinkle black sesame seeds or pour sugar water on the cooked dumplings according to your own preferences to make them more delicious.
