3. McDonald’s Black Burger
The McDonald’s black burger was released to compete with Burger King’s similarly black Kuro burger. While Burger King’s version was jet black in color due to the combined use of bamboo charcoal and a special sauce, McDonald’s burger was more often described as a dull gray color, as well as limp when compared to the promotional photos. The burger thankfully did not stay on the menu very long and was only offered for a short promotional time around Halloween.
