This recipe is for Korean Egg-Bread, usually served as a street food and known as gyeran-ppang. It is, in essence, a (small) loaf of sweetenend pancake batter with an egg baked in.
Basically, I saw this video and thought... WANT. If nothing else, Koreas a bit far for a weekend jaunt, so I had a hunt around for recipes online, and then tweaked them slightly to suit my taste.
So, there's no claim that this is particularly authentic, but it does make a good snack or breakfast.
