2. Go to the bag and cook. The plastic-sealed zongzi you buy are usually cooked, so you can directly remove the plastic bag outside, and then cook the zongzi in cold water for 15~20 minutes, or steam it in a pot for 15~20 minutes. When cooking, you can observe it and poke the zongzi with chopsticks. If it becomes soft, it is basically cooked.
3. Put it in the microwave oven to cook. Now most families have microwave ovens, so it is very simple to cook the plastic-sealed zongzi in the microwave oven. You can directly put the plastic-sealed zongzi in a special microwave oven, pay attention to the ventilation holes, and then add cold water to cook for about five to ten minutes. Because the power of microwave oven is relatively large, it will take less time to cook than ordinary gas cooker. You can also cut the bag and then put the zongzi into the water to cook, which can also save a lot of time.
