What If I Told You That Peanuts Aren't Nuts At All?

Isn't that nutty?! (Sorry, I'm not sorry.)

But you'd be wrong, because most edible nuts grow on trees, whereas peanuts grow underground in pods, which make them legumes.

According to the New World Encyclopedia, peanuts are considered a nut in the culinary sense, but "in the botanical sense, the fruit of the peanut is a woody, indehiscent legume or pod and not a true nut."

A true nut is both the seed AND the fruit (like an acorn or chestnut), but peanuts are botanically a seed that comes from fruit and can be removed from the fruit.

So when you're eating peanut butter, you're having a nut in the culinary sense — because we've coined it as a nut — but really, you're eating yourself some legumes. More like pea spread on toast, if I may.
