The Japanese version of the hot dog—Black Terra Dog—comes in a black bun.
They use edible bamboo charcoal powder to color the bun, which is over 30 cm long. It is one of the most popular street food in the Akihabara district of Tokyo.
Sesame halva is popular in the Balkans, Far East, and the Mediterranean.
Its key ingredient is tahini (sesame paste), sweetened with glucose, sugar, or honey, with various additions–pistachios, chocolate, cocoa, and vanilla or orange scent.
