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.

How to judge seltzers, plus the science of carbonation... Over the past decade, seltzer has exploded. Sales have doubled, and companies like Coke and Pepsi are buying up brands and creating their own sparkling waters. So in a crowded field, with a drink that doesn't have much flavor to begin with, how do you tell which one is best? We talk with the hosts of the podcast Seltzer Death Match to find out. Then we nerd out on the science of carbonation: What exactly is it, how does it affect the taste experience, and how do you get the best results from home carbonation systems? Dan Souza, editor-in-chief of Cook's Illustrated, has the answers.

Are the vibes at a restaurant more important than the food? Would you rip a bagel and drag a piece through cream cheese, instead of slicing and spreading? Do you tip less when you get bad service?

We’re joined by Mamrie Hart, actor, comedian and co-host of the podcast This Might Get Weird — Her new cookbook is All I Think About Is Food: A Vegetarian Cookbook That'll Keep the Party Going.
