On the list of Big Mac ingredients, there's one that stands out: the special sauce. We may not know what is in the mixture, but we know ketchup is definitely not included.
Some might think the special sauce is Thousand Island/Russian dressing, but that's not quite right. It has more pickle relish and other ingredients that can't quite be placed.
In a video of a woman making homemade Big Mac sauce using a base of ketchup, mustard, and mayonnaise, Haracz commented, "There's no ketchup in Big Mac sauce."
