Neutral classic mayonnaise
A plain mayonnaise of 200 g refined neutral oil emulsified into pasteurised yolk, vinegar, water and a little Dijon mustard: a clean base for tasting, comparing and flavouring.
Modern adaptation
A whisked, mayonnaise-based Alabama-style sauce with vinegar, lemon, honey and horseradish. The measured batch below comes from a contemporary published recipe; it is not presented as Big Bob Gibson’s original or secret formula.

Alabama white sauce is a mayonnaise-based barbecue condiment associated with northern Alabama. The Encyclopedia of Alabama credits Robert Gibson in Decatur with the sauce in 1925 and describes chickens being dunked in it. Alabama's tourism account also identifies the style as a North Alabama specialty and describes its use with smoked chicken. Those sources establish regional context, but they do not establish that the measured recipe below reproduces the restaurant's proprietary sauce.
The formula and method below follow a contemporary Food Network recipe labeled Alabama-style. It yields 1½ cups and combines mayonnaise with vinegar, lemon, honey, horseradish, onion powder, black pepper and salt. Its ingredients suggest a tangy, peppery, lightly sweet profile with horseradish pungency; this is an ingredient-based inference, not a tasting note from the source. the historic restaurant account gives a different ingredient description and is not a substitute formula.
The historical and tourism accounts describe white sauce with chicken, especially smoked chicken; the restaurant also presents its bottled sauce for several other foods. This recipe itself is a cold, whisked sauce. The cited formula gives no validated shelf life. Use commercial mayonnaise or pasteurized eggs for homemade mayonnaise, keep the sauce refrigerated at or below 40°F (4°C), and follow the mayonnaise maker's storage directions. FDA's two-hour rule for perishable food (one hour above 90°F/32°C) is general handling guidance, not a shelf-life test for this sauce.
The Encyclopedia of Alabama describes a mayonnaise, vinegar, lemon, pepper and salt sauce associated with Robert Gibson in Decatur in 1925, first used to dunk chicken and later used more broadly. Alabama's tourism account identifies white sauce with North Alabama and describes the Big Bob Gibson version's ingredients and smoked-chicken use. The measured formula here is a separate contemporary published Alabama-style recipe; the historic restaurant's proprietary formula is not claimed.
