Who Invented the Peanut Butter & Jelly Sandwich? (with The Past and the Curious)

Who invented the peanut butter and jelly sandwich? And how did it become one of the most famous lunches in America? In this episode, a question from listener Leila sends us on a trip through history to find out how peanut butter, jelly, and sliced bread came together to make the classic PB&J. Along the way, we learn about the first written recipe for the sandwich in 1901, how peanut butter went from a fancy food to a lunchbox staple, and why sliced bread changed everything. To help answer Leila’s question, we turned to our buddy Mick Sullivan, host of the history podcast The Past and the Curious. Mick loved the question so much that he made a whole episode about it—and today we’re sharing it with you.
