This combination of mayonnaise, ketchup, Worcestershire sauce and spices for dipping chicken fingers was originally created at Guthrie's—the first chain to offer chicken-finger meals—by one of founder Hal Guthrie's kids, and the sauce became a big part of the restaurant's early success. Even though Guthrie's debuted the first version of this sauce, it’s the bigger chicken-finger chains like Zaxby's and Raising Cane's that copied Guthrie’s concept and made the secret recipe iconic.
