Have you made too much chocolate for in your display case, or do you want to keep your chocolate in the best possible way? Then put it in a freezer. The chocolate stays better in a freezer than in a refrigerator. If you store chocolate in a refrigerator, the melting range changes, which also changes the taste experience. However, chocolate can be stored in the refrigerator, it is not that it is bad for the chocolate. Cover the chocolate well in advance! If you store the chocolate in the freezer, bear in mind that when it is used again, the temperature must be gradually brought back to the correct temperature.
A freezer is necessary for ice cream. Ice must be stored below freezing, because otherwise it melts.
