"Hush puppies and red slaw (also called barbecue slaw) are traditional sides for a Lexington-style barbecue," says Wall. "We've simplified the cooking procedure and added a spice rub to mimic the time over hickory and oak coals. Nothing beats meat cooked over coals, but this comes close." Begin this recipe two days ahead to brine the pork.
Note Boston butt is the top half of a pork shoulder and a common cut in the US. Order in advance here, though - your butcher will need to get a whole shoulder and halve it at the blade bone.
