Corn dogs are one of those snacks I eat once every five years or so, mostly because they need the right time and place to be enjoyed. They should be eaten on a hot, sunny day at a circus or state fair in the United States (I've never encountered them in any other country, although I haven't searched very hard). It's kind of trashy - a hotdog on a stick that's been dipped into cornmeal batter before being deep fried. But it can taste good, if the batter isn't too thick and it's fried well enough that the coating is cooked through and the hotdog inside is hot. Some vendors buy the frozen version, and if they don't cook it long enough the hotdog remains cold. The corn dog is a popular snack at fairs and the like because it's so easy to eat - the stick means you don't need utensils, although you will need napkins, especially if you coat your corn dog with ketchup or mustard. It would be even better if vendors offered sriracha (Thai chilli sauce) for drizzling but one can dream.
