Burger King introduces black buns to United Kingdom market for Halloween

This version of the burgers, however, will differ from the ones originally found overseas: They will be served just like a regular Whopper, but with a black bun.

On Tuesday, Burger King released its much anticipated Halloween Black Whopper, which is so spooky that it couldn’t wait until October. Something wicked is coming, announced the burger chain on Twitter, with a brief promo video featuring thunder and lightning and a lunar eclipse, with a burger standing in for the moon.

So, just how distracting is the color of the bun? BK has partnered up with A.1.

Odd burgers are all the rage in Japan. Steak Sauce to bake the Thick ‘n Hearty version of the sauce right into the bread (yielding both the black color and 80 more calories), and they slather the patty in A.1. too.

Burger King’s northern Europe managing director Matthew Bresnahan said: “The introduction of the black burger in Japan created a lot of excitement for Burger King fans”. Burger King made a whopper of a mistake, and there will be hell to pay.
