Israeli chef Mike Solomonov recently won the James Beard Award for outstanding chef. He created the restaurant Zahav in Philadelphia, built a food empire, and expertly hid a drug addiction from everyone in his life. He talks with Jeffrey Goldberg, the Atlantic's editor in chief, about what he felt when his brother was killed, and how the tragedy first fueled and then helped him fight his addiction. Now in a long recovery, he cooks Israeli food as a kind of cultural mission.
