This time on America's Test Kitchen, an interview with Michael Paterniti, the author of The Telling Room: A Tale of Love, Betrayal, Revenge, and the World's Greatest Piece of Cheese. We'll be tasting mayonnaise, and we'll travel back in time to discover the origins of steak tips. Then we'll head into the test kitchen to learn how to make the best oatmeal muffins. And of course, we'll be taking your calls to answer all of your cooking questions.
