Have it your way. As long as it’s a black, soggy mess.
So yes, this actually exists. A black cheeseburger featuring a black bun, with black sauce and black cheese. The Kuro Burger (“kuro” means black) is now available at Burger King in Japan. The buns and cheese are made with bamboo charcoal to achieve the dark color and the sauce includes squid ink as an ingredient. But what does it taste like I hear you ask? Well, I don’t have the inclination to put this crap inside my body. But hey, that’s what you have friends for, isn’t it? To be guinea pigs? Check out the video of my mate Aziz trying both variations of the Kuro Burger below.
