1, ordinary cake embryo. For example, we often make sponge cakes and Qifeng cakes. After baking, the surface moisture will decrease immediately, so we need to leave them for a while after releasing steam, waiting for "flooding" and softening after absorbing the moisture in the air. After completely cooling, cover it with plastic wrap and seal it, and put it in a sealed bag or box for cold storage, but remember to eat it within 3 days.

2, pound cake embryo. After the cake embryo such as pound cake is demoulded, it is necessary to brush syrup or alcohol on the surface while it is hot, or it can be jam containing alcohol, which can prevent water loss and carry out antiseptic treatment at the same time, and the taste will be moist. Cover it with plastic wrap and put it in the refrigerator, which can be stored for 2 weeks; Frozen storage can be about 1 month.
