Another failed product, this time under Grand Metropolitan's successor Diageo, was the BK Back Porch Grillers line of burgers that featured a spiced and flavored patty served on a bakery-style roll. There were two varieties: The Regular served with mayonnaise, whole leaf iceberg lettuce, tomato and grilled onions, and the Bacon Cheddar, with bacon and smoked cheddar cheese. There was one LTO variety, the Black Stack Griller, made with Black Strap Barbecue sauce (a strong molasses-flavored sauce), Swiss cheese, bacon, and onions, to promote "Men in Black II". The Griller patty was flavored so that it had a taste similar to a hamburger that had been grilled over a charcoal-fired grill.
