Trdelnik is a Czech sweet specialty from the medieval times. It was forgotten for century or more, remaining only in the proverb "rotates like a trdlo", pointing to the way of baking trdelnik on a rotating spike called trdlo. Trdelnik returned back from the old times about eight years ago.
The yeast and baking process are designed so that the sugar contained within concentrates on the surface and caramelizes there, creating the typical brown crispy shell. Finished trdelnik can be sprinkled with grinded almonds or filled with ice cream, Nutella or jam. However you should carefully select from which booth you buy it. The yeast needs to be winded on the spike very firmly so that its layer is not too thick and can be baked well. And it should be still hot when being sold.

Enjoy!
