You've seen the best cakes, smooth and sometimes with sharp edges - yet so many times despite your best efforts I'll see the unevenness (is that a word ) in my pics
I've tried rolling my mmf thick and that seems to help a bit but sometimes it seems unavoidable...any tips?
I don't use MMF but I:
trim my cake sides to make them straight
crumbcoat with BC
cover with almost 1/4 inch fondant
HTH a little
I have found my problem is frosting. I bake TWO cakes and use my wonderful AGBAY slicer to torte each cake so I have 3 layers of filling. I use 2 layers of fruit filling and the middle layer is a thick layer of frosting. This allows me to just do a crumb coat around the cake of frosting since the frosting is in the middle. Now my cakes are straight and smooth! I also TRIM the cake circle to the size of the cake so there is no extra cake circle.
Too thick fondant will give you round edges too..You need to refrigerate the cake before you put the fondant so the corner stay sharp and dont go down with the weight of it.
