Step 2: Put a proper amount of warm water into the pot, and then put all 1 tablespoon salt, 1 tablespoon cooking oil, frozen jiaozi and 1 tablespoon porcelain into the pot. At this time, bring the water to a boil with high fire, then cover the pot and cook over medium heat 1 min. When cooking jiaozi, you need to cover the pot and cook for half a minute, because as the saying goes, "Boil the skin and cover the pot to cook the stuffing". Jiaozi can be cooked quickly into dumpling stuffing only by stewing for 1 min. If you don't stew, it will increase the cooking time of dumpling wrappers, which will make jiaozi peel easily.
Step 3: Cover the frozen jiaozi and cook for 1 min, then uncover the lid, pour a spoonful of cold water into the pot, and continue to cook the jiaozi for about 2 minutes until the jiaozi floats completely.
Tips for cooking jiaozi and freezing jiaozi;
1. When you cook frozen jiaozi, you need warm water to cook it. If the frozen jiaozi is directly put into cold water, the frozen jiaozi will stick together one by one, resulting in broken skin. When jiaozi was boiled in boiling water, the dumpling skin was cooked quickly, but the stuffing inside was not cooked, which led to jiaozi's exposure. So when cooking frozen jiaozi, it is most reasonable to cook it with warm water.
2. When making quick-frozen dumplings, you need to put 1 porcelain spoon in the pot, because the porcelain spoon is equivalent to a spatula. When the water in the pot boils, the porcelain spoon rolls in the pot to prevent jiaozi from sticking to the pot.
When making quick-frozen dumplings, you need to put a little salt and cooking oil in the pot. Salt can make jiaozi eat more vigorously, and cooking oil can prevent dumpling skin from sticking to the pot.
