Why You Should Follow: Holzman is executive chef and co-owner of New York's the Meatball Shop. He started cooking at Le Bernardin at the age of 15. While you were perfecting different wanking techniques and convincing older siblings to buy beer, Holzman was putting in work. He takes meatballs seriously, and if you want to crack a joke about that, that's cool. It's encouraged even—the spot's website promotes ball jokes. But know that this sort of levity is a result of serious toil. Holzman is knee-deep in New York eats; follow his Twitter and you will be too.
