Frozen dumplings? The first thing you need to do is to make sure that you have a good idea of what you're doing.
Cold water is healthier
Dumplings are mostly filled with pork, and I'm afraid that if they are not cooked, there will be parasites. Cold water can ensure that the dumplings are cooked through, and can kill parasites, so I feel more comfortable eating them.
Cooking in cold water saves time and effort
Hot water not only takes 5 minutes to cook the dumplings, but when you put the dumplings in, you're afraid of the hot water splashing up and scalded your hands; cooking in cold water saves you time and effort in comparison, so you can just throw them into a pot and leave them there, and then you'll be able to eat them 10 minutes later.
What about freshly made dumplings?
Boiling water does not make the skin mushy
Unlike frozen dumplings, if you cook them in cold water, the skin will be mushy, and there is no temperature difference between the inside and outside of the dumplings, so it is recommended that you cook them in boiling water.
Dumplings don't stick and don't break the skin
Dumplings will be boiled for everyone, not stuck together or broken, learn this trick, dumplings are not sticking, complete and whole is the most delicious!
The first move: cook the skin first and then the filling, cover the pot to cook the skin, skim the lid to cook the filling. When the water boils, skim the lid to cook the dumplings, and the dumplings keep stirring with the boiling water, the skin of the dumplings will be cooked, then cover the lid, and it won't take long for the dumpling filling to be cooked, so you can cook it well and quickly without breaking the skin!
The second trick: Before cooking the dumplings, sprinkle some salt in the pot, so that the dumplings cooked, not only the skin strong. And each one does not stick to the pan.
