Trdelnik (Czech Cinnamon Sugar Pastry)

"So what is Trdelnik? It’s a dough that is rolled around a stick (a “trdlo”) and then grilled. Traditionally, trdelnik are then rolled in a cinnamon-sugar mixture and topped with chopped walnuts. It’s fascinating to watch trdelnik baking over the open flames! In fact, it kind of reminds me of rotisserie chicken the way it slowly rotates over the open flame. When served, Trdelnik are often filled filled with a schmear of Nutella and whipped cream. I had a trdelnik one night filled with vanilla ice cream. Delicious!"
