Kkwabaegi donut preparation in Korea

This video shows the preparation of kkwabaegi (twisted donuts) at a small bakery in Korea. There are things both similar and different to the experiences of bakers here in the west (let alone large-scale production). It's one of those "relaxing" or "satisfying" videos too, at least for the viewer, until one imagines doing it forty hours or more a week. Did you know we used to call these things "oily cakes" until the marketers came along?
