This time on America’s Test Kitchen, we speak to Harvard professor Richard Wrangham about his latest book, Catching Fire: How Cooking Made Us Human, to find out how cooking makes all the difference between humans and primates. We’ll be tasting Swiss cheese, and we’ll speak with food writer Adam Gopnik. Then we’ll head into the test kitchen to learn how to make Juicy Pub-Style Burgers. And of course, we’ll be taking your calls to answer all of your cooking questions.
