The buns, cheese and ketchup are black
At Burger King Japan, black is the new orange.
For a limited time starting Sept. 19, the fast food chain’s Japanese stores will offer two Kuro Burgers (“Black Burgers”) that swap their orange-yellow buns and cheese for ones that are pitch black, according to a press release. The Kuro Pearl features solely the black buns, black cheese and a beef patty (which isn’t black), while the Kuro Diamond adds on familiar toppings, like lettuce, tomato and onions (which also aren’t black). Both variants have black ketchup, too.
But why are the burgers black in the first place? The buns, cheese and ketchup are made with squid ink and bamboo charcoal, according to Kotaku. The black buns and ketchup aren’t anything new—Burger King Japan had unveiled them in Sept. 2012—but the addition of black cheese, however, is a novelty.
