1, it usually takes 20-30 minutes to cook. The common zongzi in the market is quick-frozen zongzi, and the quick-frozen jiaozi has just been taken out of the freezing area, and it takes a long time to cook. Generally speaking, it will be cooked in an ordinary pot for 20-30 minutes. If it is cooked in a pressure cooker, the time is shorter, and it only takes 10- 15 minutes. You can press and knead the surface of the zongzi with your hands, which proves that the zongzi is cooked.

2. When the quick-frozen rice dumplings are taken out of the refrigerator, the water inside has turned into ice cubes, and there is also a layer of frost on the surface. If you cook them directly, it is ok, but the taste is reduced, and the cooking time is long. In the thawing process, the internal cold air can be emitted. If you cook them again, the rice dumplings can be heated evenly and slowly, and the cooked rice dumplings are soft and delicious. It is generally recommended to thaw them in a cool place after taking them out of the refrigerator.
