Colonel Sanders' nephew casually revealed to a reporter a recipe that had been passed down in a family scrapbook.
Could this be KFC's closely guarded secret recipe of 11 herbs and spices? The nephew, Joe Ledington, said it is. He claims his job as a kid was to mix this same recipe in large batches.
