Can I use Buttercream to attatch a pastillage piece to my cake and various fondant pieces.. The cake is covered in MFF. Thanks for you help.
From what I know, you need to use water or clear vanilla. I'm sure someone with more experience will chime in though!!
I use water, works just fine, but i have also used RI or BC.
you can also use edible glue or chocolate. largely depends on personal preference and what you have handy, but also depends on what you are sticking on.
