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.
A syrup of this density is filtered to remove sugar crystals and calcium malate.
The filtered syrup is placed in the target containers while hot (usually 82 degrees C or more). To sterilize the stopper, the containers are turned upside down.
From crystallizing honey, you can get creamy honey.
It is enough to stir such honey intensively 4-6 times a day for 10-15 minutes and you will get its creamy form, containing very fine crystals. Such creamy honey is very good for spreading it on bread.
