1. Generally, we buy zongzi and cook it in cold water for 20 minutes. Actually, it's for the cooked zongzi. The cooking time of raw zongzi is closely related to the production technology, but it is generally better to cook at least 1 hour.

2. Zongzi is difficult to cook, so it can be cooked in a pressure cooker, saving time and effort. The cooked zongzi must be boiled before it can be put in, and the water surface must be soaked in the zongzi, otherwise the zongzi that has not been soaked in water will not be cooked anyway.

The pressure cooker boiled on the fire. When the steam starts to come out, cover the pressure valve, then turn to medium-low heat for 30 minutes, and then turn off the heat for 20 minutes. Finally, remove the pressure valve and completely release the steam. If you cook in a common soup pot, you need to cook over medium heat for more than 2 hours after the water is boiled.
