This is proudly a Shanghainese thing. Dough, green onion, oil, and salt. That's it, isn't it. And the way it's rolled ensures that each bite stays crispy on the outside, while yielding soft layers inside. This is traditional street food you can still find in Shanghai's older neighbourhoods; locals eat it for breakfast. I remember being amazed as a child, watching them flip and pull it out of the pan with their bare hands. Delicious on the street, even more so when you put in the hard work yourself.
