1. For cold storage or freezing, if the time is completely in time, it is recommended to refrigerate for more than 3 hours, which is convenient for demoulding and smoother in appearance.

2. Freezing only takes 30~60 seconds, but because of the low freezing temperature, it is difficult to handle when demoulding (if it is not covered with a large hot towel, it is easy to demould after heating, and the other side is cooled and solidified by the internal temperature of the mousse). In addition, the upper surface of frozen mousse is easy to form water ripples, but most of these lines can be eliminated by themselves with the temperature rise of mousse.
