In this podcast episode of Food Non-Fiction, we are talking about popcorn! Popcorn is made out of any variety of corn that can be popped. Corn was selectively bred from a wild grass called Teosinte, which was a very tough plant. So right from the beginning of the cultivation of corn, people were making popcorn, because corn kernels were a lot harder and popping it was one of the easiest ways to eat it. Corn spread over Central and South America because it was traded. One of the civilizations that ate popcorn was the Aztecs. They even had a word for the sound of kernels popping - "totopoca". During the Depression, popcorn was one of the few foods that actually rose in sales. This is because it became considered an affordable luxury. So vendors sold popcorn outside of theatres. Eventually, theatres started charging vendors to sell either right outside their doors or even inside the lobby. And then by around 1938, theatres started having popcorn machines inside.
