Alabama White BBQ Sauce Chicken Skewers

Alabama white barbecue sauce is one of the American South's most distinctive and least-known regional sauces — a mayonnaise-and-vinegar-based, peppery white sauce that is unlike any other barbecue sauce in the country. It was created in 1925 by Robert Lee "Big Bob" Gibson, a railroad worker turned pitmaster, at his barbecue restaurant in Decatur, Alabama, where he began basting smoked chicken with the cool, tangy, creamy sauce as a counterpoint to the deep, smoky char of the bird. For a century, Big Bob Gibson Bar-B-Q has been the gold standard of the style, and the sauce — mayonnaise, vinegar, horseradish, lemon, black pepper, and a little salt and sugar — has become the signature of North Alabama barbecue. Where most of the South reaches for tomato- or vinegar-based red sauces, North Alabama reaches for white, and the result is a chicken that is smoky, peppery, tangy, and cool all at once — a perfect summer party food.

For a party, the Alabama white sauce becomes a skewer: grilled chicken pieces brushed generously with the sauce at the end, so the creamy, peppery glaze clings to the char and the chicken stays juicy. It is a cool, tangy, smoky bite that surprises anyone who has only ever met red barbecue sauce.

Ingredients (makes 24 skewers, serves 8–12):

The Chicken: - 3 pounds boneless, skinless chicken thighs, cut into 1½-inch pieces (thighs stay juicier than breasts over a grill) - 1 tablespoon kosher salt - 1 teaspoon black pepper - 1 tablespoon olive oil

The Alabama White Sauce: - 1 cup mayonnaise (the base — use a good one; Duke's or Hellmann's are authentic Southern choices) - ⅓ cup apple cider vinegar (the bright, tangy backbone) - 1 tablespoon prepared horseradish (the gentle, sinus-clearing heat that characterizes the sauce) - 1 tablespoon fresh lemon juice - 1 tablespoon brown sugar - 1 teaspoon kosher salt - 1 teaspoon coarse black pepper (more than you think — the sauce should be visibly flecked with pepper) - ½ teaspoon cayenne pepper (a gentle warmth, not heat) - ½ teaspoon garlic powder - ¼ cup buttermilk or whole milk (optional, to thin the sauce to a brushing consistency)

For Grilling: - Bamboo skewers, soaked in water 30 minutes - Dill pickle chips and white bread, for traditional serving (the Big Bob Gibson accompaniments)

Marinating the Chicken: Toss the chicken pieces with salt, pepper, and olive oil. If you have time, let them rest 30 minutes — this seasons the meat and lets it come to temperature for even grilling. (A longer buttermilk marinade is welcome but not required.)

Making the White Sauce: In a bowl, whisk together the mayonnaise, vinegar, horseradish, lemon juice, brown sugar, salt, black pepper, cayenne, and garlic powder. Thin with buttermilk, a tablespoon at a time, until the sauce is the consistency of heavy cream — thick enough to cling, thin enough to brush. Taste and adjust — the sauce should be creamy, tangy, peppery, with a gentle horseradish bite; it should not taste like mayonnaise alone. Refrigerate at least 30 minutes for the flavors to meld. (The sauce keeps up to 1 week, refrigerated, and is better the next day.)

Grilling the Skewers: Thread the chicken pieces onto the soaked skewers, 4–5 per skewer, leaving a little space between pieces for even cooking. Grill over medium-high heat 3–4 minutes per side, until deeply charred and cooked through (165°F internal). In the last minute of grilling, begin brushing the white sauce generously over the chicken, turning and brushing, so the sauce warms and clings but does not fully cook off — you want a glossy, creamy glaze on the charred chicken.

Service: Pile the skewers on a platter and brush once more with a little extra sauce. Serve with dill pickle chips and small squares of soft white bread, the traditional Big Bob Gibson accompaniments, and a bowl of extra white sauce for dipping. The cool, tangy, peppery sauce against the smoky char of the chicken — and the pickle and bread to refresh between bites — is the authentic North Alabama experience.

The Mimosa Pairing Logic: The cool, creamy, peppery, tangy white sauce and the smoky grilled chicken call for a mimosa with bright acidity to cut the mayonnaise and a fruit profile that complements the smoke and the pepper. A classic orange mimosa is the most natural pairing — the orange's acid balances the creamy sauce and the champagne's bubbles cleanse the richness. A grapefruit rosemary mimosa is exceptional — the grapefruit's bitterness echoes the horseradish's bite and the rosemary adds a savory, aromatic note that bridges to the smoke. For a Southern, summertime pairing, a peach bellini mimosa brings a soft, stone-fruit sweetness that pairs beautifully with grilled chicken. Avoid heavy, sweet mimosas — they flatten the sauce's bright, peppery tang.

Make-Ahead: The white sauce can be made up to 1 week ahead, refrigerated, and improves with time as the flavors meld — it is genuinely better the next day. The chicken can be cut and seasoned 1 day ahead, refrigerated. The skewers can be threaded 4 hours ahead, kept cold. Grill and sauce at the last moment — the sauce should be brushed on while the chicken is hot off the grill, and the skewers are best eaten within 15 minutes, while the char is fragrant and the sauce is cool and clingy.

Pro Tips: Chicken thighs are the correct choice — breasts dry out over the high heat that produces the charred edges the sauce clings to, while thighs stay juicy and take the smoke beautifully. The white sauce is a finishing sauce, not a marinade — mayonnaise breaks and turns bitter over direct high heat, so brush it on only in the last minute of grilling, or serve it on the side; never marinate the chicken in it. The pepper should be generous and coarse — the sauce should be visibly flecked with it, and the pepper is as important as the vinegar to the sauce's character. The horseradish provides a distinctive, gentle heat that distinguishes Alabama white sauce from plain mayonnaise — do not omit it or substitute mustard. And keep the sauce cold — a warm, broken white sauce is unappealing; the cool, creamy contrast against the hot, smoky chicken is the whole genius of the dish.
