What does it take to master French cooking? This is the question that drives Bill Buford to abandon his perfectly happy life in New York City and (with a wife and three-year-old twin sons in tow) move to Lyon, the so-called gastronomic capital of France. But what was meant to be six months in a new and very foreign city turns into a wild five-year digression from normal life, as Buford apprentices at Lyon’s best boulangerie, studies at a legendary culinary school, and cooks at a storied Michelin-starred restaurant, where he discovers the exacting (and incomprehensibly punishing) rigueur of the professional kitchen.
