As Labor Day approaches my thoughts invariably turn to burgers. In fact, I have embarked on a quest to find the best burger to be had on Martha's Vineyard. And when I think of burgers the first person I think of is burger scholar and Hamburger America owner George Motz. George was such a great guest on Special Sauce a couple of years ago that listeners have been clamoring for us to reheat one of his episodes, so that's what we're posting this week. I just texted George, who told me that the fourth completely revised and expanded edition of his terrific book Hamburger America will be published next year. That's great news for burger lovers!
