Whats the difference...
There are dozens of 'buttercream' recipes. Usually, the Decorators buttercream is all shortening, and often something like the Wilton Decorators buttercream. Stable, easy to use, but not the best tasting-although many love it.
I read on one post decorator's buttercream is a 'pure' white buttercream (as previous poster stated its all shortening). Usually will use clear flavoring extracts. HTH
Decorator's butter cream is to be used for air drying flowers and freehand piping. It is a stiffer icing and usually made with shorting... I always keep some on hand in the refrigerator... will last for months.... I just make up ahead what ever I need the night before(flowers/critters) and let it air dry over night..It can be a real time saver..... Azure
