Anyone make or made this style? Recipes seem to call for ganache. I would use white chocolate as I want to make multicoloured drips. But is ganache the only way? Why not use glacé icing? If you use ganache, does the buttercreamed cake need to be chilled first? Or can it go over room-temperature buttercream? Or could it work dripped over marzipan. Does the ganache set solid?
