To learn about the role of food in our lives, I spoke to six of the world’s most successful Chefs and culinary minds; Vikas Khanna, Alain Ducasse, Heston Blumenthal, Dominique Crenn, Michel Roux Jr. and Ruth Reichl. We discuss everything from the social and cultural nature of food, the role of the chef, the science of gastronomy and the culinary arts.
