Feel for @emmalewis, that varnish buildup is a nightmare to fix once it sets in.

Seeing kids peel off the fondant and leave it is so relatable. I once tried to decorate a cake with fondant and it ended up looking like a lumpy pillow. Buttercream tastes way better, but you're right about it melting in the heat. Maybe the real trick is making fondant so thin that no one minds eating it? What do you do when you need both sharp looks and good flavor?
