I've got a cake that I'm doing an airplane theme with. The cake itself is covered in chocolate ganache. I would like to make at least the top tier look like a sky with clouds. Would it be strange to frost the ganache with a thin layer of blue frosting? I'm not sure what else I could do.
I don't ever use ganache but I'm pretty sure lots of people use fondant on top of ganache. That's probably what I would do.
what about doing a white choc. ganache and color it blue?
