Author Adrian Miller is tracking the history of African Americans via food. His specialty is Soul Food but Barbecue is his latest subject in the new book Black Smoke: African Americans and the United States of Barbecue. In the book, Adrian tracks the inextricable history of African Americans and the evolution of American barbecue via historic pitmasters. Pitmasters such as Arthur Watts of Kewanee, Illinois. Arthur, born in Kansas City, reached a modicum of fame in the early 1900s for his remarkable barbecue recipes. His pit smoked whole hog barbecue was the precursor to the annual Kewanee Hog Days. Arthur is one of many barbecue legends featured in the terrific new book, "Black Smoke: African Americans and the United States of Barbecue" by author Adrian Miller.
