I have a cake in which I made gumpaste buildings to go on the side of the cake. This may be a dumb question but I was wondering if the gumpaste will absorb the oil of the buttercream iced cake?? Thanks in advance.
I haven't done very much in gumpaste, but the little I have done I haven't had a problem. However, I can see using gumpaste on the sides of a cake as you describe could be a potential problem....I'd be worried not so much about the grease showing on the gp as it softening it up. You don't want it to fall off the sides of the cake. Can you wait until just before you deliver the cake to apply the buildings?
Hopefully I'm bumping this up for you so someone who is more experienced with gp can help.
Do you have to use gumpaste? Would fondant work out ok because fondant is supposed to go on buttercream, therefore you wouldn't have any worries.
yes it may very well do that
