Ad Hoc is a relaxed Napa Valley eatery founded by award-winning chef Thomas Keller, who turned American regional classics like barbecue into menu all-stars. For the ultimate barbecued ribs, we turned to Ad Hoc's kitchens to develop a savory sauce that makes it easy to replicate the restaurant's signature recipe at home. This Southern-style barbecue sauce layers on the down-home flavor with premium apple juice, smoked bacon and a dash of pure maple syrup.
