This delicious southern-style recipe calls for the steaks to be smoked, and if you don't own a home smoker, consider this a call to culinary arms. Or you may prefer to grill the steaks over pecan wood chips using low heat. The steaks should be marinated for ten to twelve hours, so begin the process early in the day. The marinade serves a double purpose, since it's boiled to make a tangy barbecue sauce. Sassafras, one of the ingredients in the marinade, is the herb derived from tree bark used for flavoring root beer. It's also one of the components of file powder, and essential seasoning in Creole cooking.
