Matters needing attention in steaming steamed bread

1. Steam steamed bread with cold water, so that steamed bread can be slowly heated and revived for the second time. If the steamed bread suddenly encounters high temperature, there is no way to revive it for the second time, so that the steamed bread will not be fluffy and delicious.

2. Steamed steamed bread can't be opened immediately. If you open the lid immediately, the steamed bread will suddenly shrink when it gets cold, so it will become very hard. In order to avoid this situation, we can turn off the fire and simmer for 3-5 minutes, then open the lid, so that the steamed bread is not easy to collapse and deform.
