You should ask one of the other posters, but I think they are a fried bread that is coated with sugar and cinnamon. They are long and skinny usually, almost like a licorice stick. I’ve seen ‘em a million times at street fairs etc. but never tried one.
My grandson had his first one when we were at Disney in LA several years ago. Made on the spot by a street vendor. They became his very fav food.
