White Sauce Chicken, Perfected on the Pit
At Big Bob Gibson Bar-B-Q, the chicken begins with slow hickory smoke, its skin bronzed and crackling, before a dip in the iconic white sauce. The result is silky tang meeting deep smoke, anchored by black pepper and vinegar brightness.
Each piece carries moisture locked from the pit’s steady heat. Guests often order half-chickens, pairing them with slaw or potato salad. The sauce clings but never overwhelms, designed to complement—not mask—the bird.
It’s a harmony of texture and temperature. One plate converts skeptics; two plates make lifelong fans.
