Roy Blount Jr. is one of the funniest writers on the planet. And he loves to eat, and talk about what he's eaten, so he's a made-to-order guest on Special Sauce. On this week's episode, you'll hear Roy wax poetic about the dangers of eating foam (he's "anti-abstract and pro-substantial" when it comes to food) and why we should all save room for pie, which, not so coincidentally, is the name of his new book.
