Fresh dumplings can be cooked for about 7 minutes, while quick-frozen dumplings take a long time to cook, which takes about 1 minutes.

generally, after boiling three times, turn off the heat, take out a dumpling and open it to see if the stuffing inside has melted and the outer skin is cooked, and then you can decide whether to continue cooking or turn off the heat.

put a proper amount of cold water in the pot and bring it to a boil. Boil the dumplings in boiling water. When the water boils again, add a spoonful of cold water to keep it boiling. So for three times, when the water boils again and the dumplings have all floated on the water, you can turn off the fire. At this time, the dumplings are ripe and ready to eat.
