The bought zongzi can be steamed for 10- 15 minutes. Generally, jiaozi bought outside is cooked in jiaozi, which is cooked when it is made. You just need to heat them thoroughly after you get them. At high temperature, they can be completely heated within 10- 15 minutes. Raw zongzi is not easy to cook, and the heating process takes a long time. In order to steam zongzi thoroughly and make it softer, it is more appropriate to steam it in a steamer for about an hour, and then stew it for half an hour after cooking. Zongzi is a nutritious food, which contains vitamins, minerals, protein, dietary fiber, carbohydrates and other nutrients. Proper consumption is good for health.

The method of making zongzi is as follows: firstly, treat zongzi rope, cook and wash zongzi leaves and zongzi shreds, then cut off both ends of zongzi leaves, tear zongzi shreds into appropriate length and thickness, then wash glutinous rice to make it swell and add plain oil, then start to wrap zongzi, take the smooth side of zongzi leaves, fold it into a funnel shape and put it into glutinous rice until the funnel is full, and finally fold the remaining zongzi leaves and tie it with zongzi rope. Put all the zongzi into a pressure cooker, the height should not exceed two thirds, add clear water, cover and cook until the height of zongzi is flat, and turn off the heat for about an hour, depending on the size of zongzi. Cooked zongzi can be eaten without cover until it is naturally deflated and can be frozen after cooling.
