Dan Barber questions “Who’s the farmer here, and who’s the chef?” after witnessing the production of natural foie gras. Normally the epitome of unnatural food, most foie gras is made by force-feeding geese copious amounts of grain in a process called gavage and slaughtering them while their livers are enlarged. But after a visit to a unique Spanish farm, Barber believes that the future of food could consist of working in concert with natural patterns and animal behaviors rather than against them.
