Tune in to the America's Test Kitchen 4th of July special. This year, it's all about American beer. We speak with historian, author, and self-proclaimed ranter Maureen Ogle about her book Ambitious Brew: The Story of American Beer. We'll be tasting barbecue sauce, and we'll taste test beer with expert Lauren Clark. Then we'll head into the test kitchen to learn how to make the best Memphis-style ribs at home.
