Jamie Oliver is not only Britain's best-loved chef--he just might be the most popular chef in the world. But it's not just his culinary skills that have made him a household name in both Britain and America. His boyish good looks, infectious enthusiasm, and hip, matey appeal have won him the kind of adulation usually reserved for pop stars. More than a young icon, his dynamic TV series "Jamie's Kitchen--in which he trained 15 unemployed kids to be chefs--revealed a serious individual with deep-held concerns about youth, work, and society. Now, media critics Stafford Mildred and Tim Ewbank talk to friends, family, and colleagues as they trace Jamie's rocketing rise to the top.
