I am taking a cake decorating class and my instructor said not to use any plastic when making or storing Royal icing because it will break it down. Is this really true? I have a mixer that is all plastic – does this mean that I can’t use it to make the icing?

Fats and oils are what break down Royal Icing, and it is very difficult to completely clean fats and oils from most plastic containers. If, however, you use brand new plastic containers, or you use the same container always for Royal Icing only, you should have no problems. If your mixer is plastic, just make sure the beaters are completely clean, with no fat residue. If you have any doubt, wiping them with white vinegar can help.
