More than almost any other Unfiltered guest so far, you know exactly who Jamie Oliver is. Except, you don’t. In a revealing and impassioned interview with James O’Brien, Jamie takes us back to being a young boy in Essex working in his parents’ pub, not only discovering his passion for food, but his passion for what food can do. The Naked Chef saw Jamie become a household name overnight, and while he may have sold a few cookery books off the back of it, his fame enabled him to pursue the thing that he’s best known for: trying to make a difference.
