For a time, large-scale boiled dumplings were popular in southern China, so it took so many years to slowly replace the Lantern Festival and become a special snack of the Lantern Festival. Except for a few areas in the south who insist on packing jiaozi at home, people in most parts of China buy frozen jiaozi, which is also very common in the north. This kind of cooked frozen dumplings can be different from cooked fresh ones. If you are not careful, you will boil into a pot of "sweet glutinous rice porridge". I firmly believe that many friends have a big rollover moment when cooking dumplings. I still remember that in the early years, when I just cooked the quick-frozen jiaozi at home, it was common to leak stuffing when cooking. Sometimes, I am afraid that the cooked jiaozi is slightly undercooked, and it is often half-cooked with stuffing and cold ice.
Temperature difference is the most important factor. What is the key reason why dumplings often leak stuffing and are half cooked? Temperature difference is the most important factor. Therefore, people usually put the frozen jiaozi in the freezer of the refrigerator. What's the temperature in the freezer of everyone's washing machine? MINUS 16 degrees. Most people know that the ambient temperature of water after boiling is 100 degrees, which is a total temperature difference of 1 16 degrees. So the dumplings that have just been taken out of the refrigerator are steamed with boiling water immediately. If it's not cooked, I'm really sorry for such a big temperature difference, and it's easy to be half cooked. So how to cook frozen dumplings correctly? Cooking glutinous rice balls with boiling water is a no-no, do 1 step by step 1 step, the glutinous rice balls are smooth, sweet and do not leak stuffing;
Therefore, the key step of cooking jiaozi correctly is to pay attention to how to reduce the temperature difference. The key to doing a good job is three points:
1, connect the soft refrigerator in advance. At present, refrigerators at home have cold storage rooms and soft freezing rooms. It is best to heat the jiaozi in the soft freezer five or six hours in advance or one night. In that case, the dumplings will be heated from MINUS 16 degrees to above 0 degrees.
2, the gap between boiling water, the indoor temperature is idle again. Here, cold water is introduced into the pot and gradually heated; At this time, it is necessary to take the jiaozi out of the soft freezer, reach the indoor temperature, and then further heat it to minimize the temperature difference.
3. Cook jiaozi in warm water. In order to avoid water leakage in jiaozi, you should be careful not to put it into water after boiling. Although the temperature in jiaozi is close to 0 degrees at this time, there is almost a temperature difference of 100 degrees, and it is easy to boil. You have to cook jiaozi with warm water of more than 80 degrees, and the temperature difference is reduced by more than 20 degrees. Heat jiaozi's tea soup to a bottom pot full of bubbles, and hear the creak of water. At this time, the temperature of water exceeds 80 degrees.
Adding one more thing is smoother. Before you put the glutinous rice balls, you need to remember a lot of 1 things, which are the "edible salt" of every household. Not much, half a pot is full of water, add about 3 grams of edible salt. At this time, when jiaozi is put in, the whole process should be heated with slow fire, and the tea soup in the pot should be pushed with the back of the spoon to generate running water, so as to promote the jiaozi to rotate in the pot and prevent it from sticking to the bottom of the pot. Boil jiaozi until it floats and bulges, and jiaozi will be cooked. When wrapping jiaozi, you have to put jiaozi into the bowl with a spoon and a little tea soup to prevent jiaozi from sticking to the bowl.
When cooking jiaozi, it is wrong to boil the water and then put it into the pot. Do 1 more things and 1 more steps. Jiaozi is sweet, smooth and unbreakable.
