DAVID GREENE, HOST:
And if you're watching a hockey game, basketball game, I mean, what better way to enjoy it than with some nachos, pretzels, maybe some hot dogs. Well, Josh Chetwynd knows a thing or two about stadium grub. He is the author of "How the Hot Dog Found Its Bun: Accidental Discoveries and Unexpected Inspirations that Shape What We Eat and Drink." And he is in the studios of Colorado Public Radio. Josh, thanks for joining us.
JOSH CHETWYND: Thanks for having me.
GREENE: I don't know if I've ever given a lot of thought to how the hot dog bun came about, but you have uncovered the story of how it came to be. Tell us the story.
CHETWYND: Well, amazingly, a lot of people have given thought to it; in fact, there are a number of people who have claimed to have brought together this gastronomic combination, this great marriage. The best story comes out of St. Louis in the 1880s. And there was a street vendor who was selling - at the time they weren't called hot dogs, they were called either red hots or frankfurters - and while selling them he would give out white gloves. Because when someone would buy the red hot, they wouldn't want get their hands scalded or wouldn't want to get too greasy. The problem was is that a lot of the patrons were running off with the gloves. This was really hurting his bottom line. What he ended up doing was going to a brother-in-law of his and saying, look, I have this problem and it was lucky enough that his brother-in-law was a baker and suggested the soft roll.
GREENE: Well, that's the story of the hot dog bun. OK, can we talk nachos?
CHETWYND: Oh, absolutely. I can always talk nachos.
GREENE: A snack for army wives? Is that really how they came about?
CHETWYND: The story of the nachos occurred in a Mexican border town just over the border from Texas. And there were some Army wives who would go over to this small Mexican town to just shop and to enjoy the ambiance. And one day they went to a local restaurant, and it was at sort of an off-hour. But the maitre d' let them in. His name was Ignacio Anaya. And Ignacio took just little pieces of what he could find inside the kitchen and threw it together, and put together what was the first plate of nachos. And what I love about the story is that even though it was of Mexican birth, the type of cheese he used was Wisconsin cheese.
GREENE: Well, do you have a favorite discovery in this book? You sure cover a lot of ground.
CHETWYND: The book is really - the main theme is about luck. And I think my favorite kind of luck is the unexpected inspiration. And those are situations where a person really has a completely different idea in mind. It's just lucky to kind of stumble across a great item. And the best story along those lines is the graham cracker. There was a gentleman by the name of Sylvester Graham and he invented it, because he thought it would be a deterrent for people's sex lives.

CHETWYND: And thought - he lived in a time where foods were becoming processed and he thought that part of that processed food and sort of very rich foods led to people being a little too focused on their libido. And I can only imagine as a guy who thought that processed foods and sugars were bad for you, what he would have thought of s'mores nowadays using his graham crackers.
GREENE: Well, we'll never think of s'mores in the same way. Happy eating, Josh.
CHETWYND: Thank you.
