Have you ever had to “fix” a cake? Taking it out of the pan after baking somehow caused a monumental hole to appear in the layer, and the only resolution was half a can of frosting to fill it? If you make this mistake often enough, you figure out how to make the layers smooth and unnoticeable to the visually keen. At least that’s what I’ve heard.
With that in mind, I think we should be hiring cake decorators to fill the pot holes in the roads. Someone who’s used to fixing mistakes in cakes should be good at it!
