I attempted to look at the history behind Chinese leek boxes also known as Chinese chive pockets (as well as any combination of the two), but there wasn’t really much. I assume this is because that they are typically grouped together under the larger umbrella of “jiaozi” or dumpling.
Essentially, they are little pockets of dough filled with Chinese garlic chives, bits of egg, and occasionally some type of meat. They are pan fried and can be manipulated into any shape that you want. You make the dough, fold the filling into them, and simply fry them on a pan!
Some pictures below of the process 🙂
