Introduced as the ‘Kuro Burger,’ it composes of a black bun, meat with black pepper, and black cheese. The bread and cheese contain bamboo charcoal, popular in Japanese cuisine.
The burger also comes with an onion-and-garlic sauce made dark with squid ink.
Burger King is offering Japanese customers two varieties of the Kuro — the Pearl and the Diamond. The Kuro Pearl is filled with basic ingredients (listed above); the Kuro Diamond is spruced up with lettuce, tomatoes, and onions, which add a little color to the black burger.
Burger King’s Kuro Pearl and Kuro Diamond are available only in Japan, for a limited time.
