2. The boiled zongzi needs to be soaked in water, but not directly in cold water. After the zongzi is cooked, don't rush out of the pot, put it in the pot and soak it. If you cook zongzi with ordinary aluminum pot, you need to soak it in the pot for about 1 hour before you can take it out. If you cook zongzi in a pressure cooker, you need to stew it in the pot for about 20~30 minutes after turning off the fire, which can make the taste of zongzi more sweet.

Zongzi is a kind of cooked food. The shelf life at room temperature is generally only a few days to a week, and refrigeration can only temporarily extend the shelf life. If zongzi smells bad or musty after opening, it can't be eaten.
