New Jersey-born chef Tom Colicchio says there's a reason that he and other chefs with Italian roots from his generation didn't open Italian restaurants, until now. "We didn't open Italian restaurants," he said. "We did French restaurants because that was our training." Now, the "Top Chef" lead judge has opened his first Roman trattoria, Vallata, named after the town in Italy where his family is from. Colicchio reflects on his Italian roots and shares the memories he has of being in the kitchen with his mother and catching clams for dinner with his grandfather.
