Funny thing is that croquembouches didn't exist at the time. At least from what I managed to google Beauty and the Beast is set around 1740 (the time the original novel was written) while the croquembouche as we know it today was invented by a French chef in the late 18th/early 19th century. But the site also says that something like the croquembouche existed since the 1500s but it wasn't really the same thing, so it's hard to tell.
Fuck off, Belle. I don't see you contributing to the economy. That shit was probably tasty.
