Nowadays, many people choose to buy vacuum dumplings in the supermarket for convenience. Vacuum jiaozi is usually cooked. Even if you take it home and freeze it in the refrigerator, you can eat it after cooking for about 20 minutes. But if it's raw rice dumplings wrapped in raw glutinous rice, it's better to cook more on the safe side. Raw zongzi is difficult to cook, and it will save time and effort if there is a pressure cooker.
