Fried Dough Around the World. I had no idea there were so many versions of fried dough. I only know about doughnuts, churros, and you tiao (from China). And I learned this little bit of trivia: \”Doughnuts only took their torus shape to overcome a problem inherent in balls of dough – uncooked centers. Removing the centers ensured that the doughnuts would be cooked throughout.\”
