Vanilla Extract
The complicated process that needs to happen to grow real vanilla beans means it’s one of the most expensive per-unit foods in your grocery store, and the price-per point of vanilla beans means that extract can be mind-bogglingly expensive.

Vanillin is a lot cheaper, though, and that’s because it’s a byproduct that can be extracted from things like coal and wood.
