This is a family style dish from the Northern region in China. Usually you can find these on a menu of a Chinese restaurant that serves dumplings. My mom always kept homemade ones in the freezer. If you like pan fried dumplings or gyoza, these taste like you are eating the outer fried dough of those. If you have had these before you will remember the flaky, layered texture of each bite. They are nothing like a pizza crust. That is from the the the flattening, the rolling, the twisting, then the flattening again.
It’s a great vegetarian alternative to dumplings and can be served with various soy dipping sauces. You can slice up slivers of ginger, douse it with some hot sauce, or keep it simple and just add sesame oil.
