Cake preservation method: the kitchen paper towel is slightly wrung dry after being wet, and it is advisable not to drip into the water. Because paper towels can't be laid directly on the cake, you can make a cylinder around the cake with other hard paper shells behind the calendar paper, which is slightly higher than the cake body. Cover it with a wet tissue and wrap it with plastic wrap. If the bought cake has been packed in a paper box, open the lid, put a wet tissue on the edge of the box, then cover it and wrap it with plastic wrap. Then put it in the refrigerator for freezing. If you take it out a night or a day in advance and put it in the refrigerator to thaw naturally, the cake will still maintain its original flavor and moist taste, and you can hardly feel the difference before freezing. This freezing method is suitable for cakes without whipped cream and fruit. If there are cream cakes and fruits, don't freeze them. Try to eat it.
