Since I learned a few tricks from the celebrities, the bread of the little rice family has been "forever young". Good ideas are naturally shared!
One way is to pour half a pot of warm water into the steamer and add some vinegar, then put the steamer, put the dry bread on the steamer and cover the lid. Do these things well before going to bed at night, and you will get up the next morning to eat brand-new good bread.
It doesn't matter if you are traveling or on business. Wrap the bread in its "original" packaging wax paper, then wrap a layer of paper soaked in water on the wax paper, then put it into a plastic bag with the inner layer soaked in water, and tie the bag tightly, and the bread will be soft again overnight.
Or put the dried bread between two pieces of fresh bread, tie the mouth of the packaging bag tightly, and put it down at room temperature for half a day, and the bread will become soft.
In order to prevent bread from drying, hardening and slag dropping, it is best not to put it in the refrigerator or with biscuits except fresh milk bread and bread with cream, meat and eggs.
