I have been using IndyDebi's buttercream for several months and love it. Everyone loves the taste and I love that I can get it nice and smooth.
My only problem is that it hardens very quickly making it difficult to attach decorations. Am I making it too stiff? It goes on well enough but by the time I am done smoothing(takes a while I am a newbie) it is already set where I started. I find using water works a bit but it doesn't always hold.
Should I use piping gel to attach fondant pieces?
Any other suggestions?
Adding more fat/crisco will slow the crusting time down and give you a little more time work with it.
You can use piping gel, vanilla, corn syrup, or gum glue to attach the fondant pieces.
I use Indydebi's buttercream most of the time. I like that it crusts failry fast. I use a little sugarwater "glue" to attach decorations. It's not any different than attaching decorations to fondant. Fondant is always "dry" when I add the decorations. I just use the same method when applying to buttercream.
