Don’t bother asking the chef Tom Colicchio to name a dish that’s a standard crowd pleaser at home. As he has often said, his last meal would be his mother’s gravy — which, for an Italian from New Jersey, is tomatoes, meatballs, and braciole over macaroni, otherwise known as pasta. But when it comes to dinner with his wife and kids, Mr. Colicchio rarely makes the same thing twice. “There’s nothing favorite. It changes from time to time. I don’t like to repeat myself.”
