Burger King unveils all-black burger in Japan

Just in time for Halloween (we guess???), Burger King has unveiled an all-black cheeseburger in Japan.

The sandwich has a black bun, some kind of black sauce and even black cheese oozing out the sides.

It almost doesn't look real. But it is.

Burger King Japan says the cheese and buns are made by smoking them with bamboo charcoal. The sauce is made with onion, garlic and squid ink, according to Kotaku.

The beef patties also contain black pepper.

There are two types of burgers: the Kuro (Black) Pearl and the Kuro (Black) Diamond with all the fixings. They go on sale later this month in Japan for a limited time only, so book your trip to Tokyo soon than later.

If you're feeling brave.
