If you can't finish eating the ice cream cake that day, it is still recommended to put it in the refrigerator for preservation, so that it can continue to maintain the sweetness of both cream and ice cream, as well as the dense taste of the cake.

Ice cream cakes need to be frozen if they need to be kept for two or three days. Because the temperature of the refrigerator freezer is generally 4-8 degrees, under this temperature condition, if stored for a long time, ice cream and animal cream are easy to melt, and the taste and cake shape will become worse after melting. Therefore, it is suggested that if you need to keep it for a long time, you should choose to keep it frozen and wait until you take the ice cream cake out of the freezer in advance and melt it naturally.

The origin of ice cream

As early as 1000 years ago, feudal princes asked people to take ice in winter, store it in the cellar and take it out in summer to enjoy it. At the end of the Tang Dynasty, people mined a lot of saltpeter when producing gunpowder, and it was found by chance that saltpeter would absorb a lot of heat when it was dissolved in cold water, and even make water freeze.

Since then, people can make ice in summer without storing ice. At this time, there are merchants who specialize in selling ice in summer. They add sugar to the ice to attract customers. In the Song Dynasty, there were more patterns of frozen food in the market. Merchants also add fruit or juice to it. Merchants in the Yuan Dynasty even added fruit pulp and milk to the ice. This frozen food is considered as primitive ice cream.
