Okay... So I bought a bunch of books and tried my first fondant cake (it was horrible) but I learned a lot and now know a lot of different ways to fix the issues I had before. The crumb coats always call for icing. Do you like to use a buttercream for that or is it a different type of icing and then a buttercream on top?
Welcome to Cake Central. the crumbcoat under fondant is just enough to provide s smooth finish. You can use almost anything, just sparingly.
If you put too much icing under the fondant, it will allow dimples and/or slipping.
Keep trying, you'll get it.
I always use buttercream under fondant. As JoAnn says, don't make it too thick or your fondant will wrinkle and bulge. Some people use simple syrup and similar type coatings under fondant.
Thanks.. I have a recipe for a simple syrup. I'll try that.
