I'm in the process of making DSs birthday cake. I've got Debbie Browns book and it doesn't really mention trag gum/ cmc, but most YouTube tutorials that I've watched say it is needed. I'm making a Madeira cake, icing it with fondant and then making his comforter teddy out of fondant to sit on top as well as some cubes with each letter of his name. Will I be ok without cmc? Or will I be better off with it?
