What is it?

Essentially, it's dough rolled on a stick that is then baked over coal burning fire and topped off with sugar and your choice of topping: cinnamon, vanilla, almonds, cocoa.
Sound familiar? I thought it was the German's knüppelteig at first sight.

I stumbled upon such a delicious delight during my venture through old town Prague. Not looking for dessert at all but I had to try it & I loved it.
