Dan Barber is a respected chef. He’s very big into sustainable food and Blue Hill, his famed restaurant, is actually a part of Blue Hill Farms. Last year, Barber spoke about Foie Gras, the much maligned cuisine that has taken a beating in the press (and for good reason).
His talk appeared on TED, one of the best video sites I have ever visited. In the talk, Barber discusses the methods of farmer Eduardo Sousa. It’s a very interesting piece.
