The difference between boiling dumplings with the lid on and without the lid is the purpose: open the pot to cook the fillings, and cover the pot to cook the skins.

First add water to the pot, wait until the water is completely boiled before adding the dumplings, then stir it two or three times with chopsticks, and then cover it immediately. Don't leave the stove at this time, wait patiently until the water boils, then open the lid and add cold water to lower the boiling point in the pot and prevent the dumplings from breaking due to thermal expansion and contraction.

After the water boils again, add cold water twice more. When it boils for the third time, the dumplings will be fully cooked. This method will not break the skin easily and can maintain the best taste of the dumplings. .

If the fire is too low and the soup cannot boil for a long time, the dumplings will sink to the bottom of the pot and become rotten. If the fire is too high, the pot will inevitably overflow when the lid is closed, so after the water is boiled and the dumplings are placed in the pot, use a spoon to push the water and dumplings in the pot, then cover the lid and turn on the high heat to allow the water in the pot to quickly fill up. Open up.

At this time, adjust the size of the fire. No matter whether the lid is open or covered, as long as the water in the pot keeps rolling and does not overflow. After cooking for a few minutes, the dumplings will float. Take one out and press it with your fingers. As long as the skin of the dumpling is soft, it is basically done.

How to cook dumplings without breaking the skin

1. Add salt: When cooking dumplings, add a small amount of salt to the boiling water, and wait until the salt dissolves before adding the dumplings. The dumplings have a strong skin that doesn't stick to the pan or break, and they won't overflow the pan when cooked.

2. Stir along the edge: After the dumplings are put into the pot, use a spoon to go down from the edge of the pot and push the dumplings in one direction to prevent them from sticking to the bottom of the pot. Be sure not to flip it back and forth or randomly, otherwise the dumplings will be spoiled.

3. Do not use high heat: When cooking quick-frozen dumplings, it is not advisable to use high heat. Unlike fresh dumplings, the skin is not easy to break when cooked over high heat. Cook slowly over low heat so that the dumpling wrappers are not easily broken.

4. Put in boiling water: After the water is completely boiled, put the quick-frozen dumplings in. Don't put it in too early, otherwise it will stick together easily, and stir it thoroughly after putting it in so that the skin will not break due to sticking together.
