This Alabama white sauce is incredibly easy to make. It was invented in 1925 by Robert 'Big Bob' Gibson at Big Bob Gibson's Bar-B-Q restaurant, in Decatur. Don't let this mixture's appearance stop you from trying what is a devastatingly delicious marinade, basting sauce, and serving sauce.
This Alabama white sauce is a versatile condiment. For optimal flavor development, prepare it at least 2 hours, or ideally a day, in advance to allow the flavors to meld. When selecting mayonnaise, a high-quality, full-fat variety will yield the best creamy texture and rich base. Adjust the horseradish and cayenne pepper to your desired level of heat. For an extra layer of complexity, consider adding a pinch of smoked paprika or a dash of Worcestershire sauce, though traditionalists may prefer the classic profile. Always taste and adjust seasoning before serving. This sauce is excellent on grilled chicken, pork, or even as a dressing for coleslaw.
