Nachos: They’re one of the most popular snack foods in the United States, and the name is instantly recognizable worldwide. Bright yellow nacho cheese is now a staple at countless sports events and movie nights, serving as a flavor of nostalgia to many.

But nachos’ immense popularity over the years has overshadowed their true history. The first nachos weren’t invented in ballparks or designed for concession stands. They were created 80 years ago in a small town in Mexico, along the south Texas border. And they weren’t made to be a big hit. Still, nachos would end up bigger than anyone could have ever imagined.
