Japan seems to be the center of all weirdness. Burger KIng Japan has now decided to introduce black burgers to the Japanese market. It is known as Kuro (ie black) burger and comes in two varieties: diamond and pearl.
You can buy the Kuro Pearl for 480 Yen (£2.76) while the Kuro Diamond’s price is 690 Yen (£4). Currently, it is available for only a limited time.
So how are these black burgers made? The black color is got by using bamboo charcoal and the black sauce comes from squid ink.
