Erin, you barge right in anytime smileys/smile.gif more info...
afterall, you are the Czech expert here.
I did not try them, they looked interesting, but it's basically dough wrapped around a stick, roasted, and some sugar burnt on it. They're probably wonderful, but I was investing my calories in things richer, creamier, and more chocolately. They did smell wonderful. I just couldn't figure out why they weren't filling them with pastry cream after they came off the stick! I need to go to Prague, set up this concession correctly, and make big the Big Koruna.
I recently saw a food/travelelogue program where they were making these much further east. I looked them up and they originally came from the Transylvania area, migrated into Hungary (which was all Austro-Hungarian Empire then), then a Hungarian gerneral brought them into Slovakia (still Austria-Hungary). Appparently the migration continues and they finally made it to Prague, in Czechia, which was part of Austria-Hungary as well.
