We ate lunch at a BBQ place in N. Carolina this past May. They had several bottles of sauces to choose from including a Mustard sauce, White sauce, Red Vinegary sauce, Hot sauce and Kansas City sauce. All of the sauces except the Kansas City sauce were cider vinegar based. We tried them all but I must say we don't care much for the vinegar based sauces. We must have a sweet tooth.....or two...
