1: put the egg beater and scraper in the freezer before sending them away 15 minutes. 2. Operate in an air-conditioned environment until it is open to 18 degrees. 3. Refrigerate the cake 1 hour and then decorate it. 4. When decorating flowers with a decorating bag, because the hands are also warm, it is inevitable that the light cream will melt due to the hand temperature when squeezing. At this time, you can freeze an ice pack in advance, and you can touch the ice pack before decorating, so as to lower the hand temperature, and then quickly decorate the flowers. 5. Feel that the hand temperature has increased, and continue to touch the ice pack, so that the problem of cream melting can be better avoided.
