While working the peanut butter off the roof of your mouth, have you ever wondered who came up with the PB&J?

The staple sandwich of childhood hasn’t been around as long as you think. It’s actually a more recent invention.

Peanut paste, as it was called then, wasn’t that great until Joseph Rosefield developed a way to keep it from separating. He called it Skippy.

And even though jellies and jams had been around for a long time, World War II brought the dish to mass appeal, as soldiers enjoyed a bite for an energy boost.
