I've said that I will attempt to make a cake for a friend who is on a wheat and dairy free diet. I have a suitable cake recipe, and fondant is fine, but does anyone have any suggestions for a crumb coat/ undercoat? Buttercream is out, obviously, and ganache. I can't think of anything else :-(
If all else fails I can do a design which doesn't require a smooth finish to the fondant, but I'd like to try if I can.
