I am making a cake covered with IMBC and gumpaste roses. The customer wants to pick the cake up Friday for a Sunday celebration.
Question - can gumpaste flowers keep on a buttercream cake in the refrigerator for two days. I know fondant does not like refrigeration but not sure about gumpaste.
Unfortunately, gumpaste doesn't care for it a whole lot, either, although it might not react as violently as fondant. I would really try to make sure the cake was wrapped airtight while in refrigeration and then unwrapped only when it had reached room temperature. Of course, I know this depends on how humid it is where you live. If it's a dry climate, there are people who refrigerate fondant and gumpaste without covering it. I live where it's very humid so I'm really careful about this sort of thing, but when I make cakes in Mexico City, which is cool and VERY dry, all the rules change.
