A recipe for hickory-smoked chicken sandwiches served with tangy, mayonnaise-based white sauce originated in 1925, when railway worker Big Bob Gibson dug a pit in his backyard in Decatur, Alabama, nailed a plank-oak serving table to a sycamore tree, and started smoking barbecue for friends, co-workers, and passersby. His popular recipe eventually spread to barbecue joints throughout the region. What distinguishes this dish is a creamy sauce that bastes and dresses the chicken. This recipe first appeared in our June/July 2011 BBQ issue along with our story Classic 'Cues.
