Alabama White Sauce Smoked Chicken

The dish is credited to Big Bob Gibson, a railroad worker who from 1925 cooked pork and chicken in a hand-dug pit in his Decatur, Alabama backyard, serving from oak planks nailed to a sycamore tree. He combined mayonnaise and vinegar into a white sauce, originally to baste and keep the whole pit-cooked chickens moist; it became the restaurant's hallmark. Big Bob Gibson Bar-B-Q remains family-run across four generations, and the sauce spread regionally to north Alabama smokehouses and was bottled for retail in the mid-1990s.

The skin comes off the smoker burnished and smoky; the sauce hits cool against the hot bird, sharp with vinegar and horseradish, peppery, and creamy without being heavy like a dressing. White meat stays juicy because the sauce both bastes during cooking and dresses after. The acid cuts the smoked fat and the black pepper lingers. It tastes nothing like sweet barbecue — tangy and savory, with the smoke underneath the cream.

Chicken is smoked at roughly 250-300°F (121-149°C) until the breast reaches 165°F (74°C) and the thighs are higher, so the lean breast does not dry while the dark meat cooks through. The white sauce is an emulsion: mayonnaise is already an oil-in-water emulsion stabilized by egg yolk, and the vinegar's acid (and the sauce's salt) thins it to a pourable, clinging coat while heightening tang. Because dairy-free mayonnaise tolerates gentle warmth better than cream, the bird can be dunked hot without the sauce breaking immediately. Hickory smoke supplies the savory, phenolic backbone the sharp sauce plays against.
