Animal cream can't be frozen, once it is frozen, it will go bad. Cream should be kept in the freezer, and the temperature should not be lower than 4 degrees. The maximum temperature of household refrigerator can only be adjusted to 6 degrees, and it is unstable, so take a towel and wrap the frost outside the refrigerator near the door, not inside, because the innermost back wall of the refrigerator is a refrigerated place, which is the coldest and most vulnerable to frostbite, and frostbite can not be sent away.
