This week's guest claims that without fruits we'd still be swinging from trees eating bugs. Fruit-obsessed journalist Adam Leith Gollner joins us for a look at the fruit leggers and their stories as told in his book The Fruit Hunters: The Story of Nature, Adventure, Commerce and Obsession. The Sterns experience a religious moment at the church of heavenly barbecue - Louie Mueller's in Taylor, Texas. Wine maverick Joshua Wesson talks cool wines for steamy days, and food scientist Harold McGee, author of On Food and Cooking: The Science and Lore of the Kitchen, explains what's really going on with those color-enhanced steaks in the meat case.
