Here’s a revealing documentary about what is perhaps America’s most controversial food: foie gras. Made by Zagat, it tries to examine all sides of the story. From the farm that supplies the fattened duck liver to the chefs who cook the buttery meat goodness to the organizations that oppose the concept of force feeding animals to the animal experts who understand the biology of ducks best. It’s an interesting watch.
