Food critic Brian Reinhart fell in love with spicy Mexican cuisine as a teenager in Texas, but over the years he started to notice that the jalapeños he’d buy in the grocery store were less and less hot. So he called up an expert who studies chili pepper genetics, and she shared a shocking revelation. In this episode from our friends at the Slate podcast Decoder Ring, host Willa Paskin tells the story, then talks with Los Angeles Times columnist Gustavo Arellano, who puts the jalapeño in the context of an age-old cycle in the American obsession with Mexican food.

Brian Reinhart’s article about the jalapeño ran in D Magazine. Gustavo Arellano’s book is called Taco USA: How Mexican Food Conquered America
