westley, Exactly what is the special B/K Stacker "Special Sauce"?
Inquiring minds want to know
Hahaha! It was like McDonald’s "special sauce" — like thousand island dressing. I see from wiki that it’s called "stacker sauce" — The BK Stacker sandwiches consists of two, three, or four beef patties, "Stacker" Sauce (a Thousand Island Dressing variant), bacon and American cheese.
So that’s what I should have received before when they used bbq sauce!
