You can freeze these dumplings! Line the finished dumplings on plates or a baking sheet and stick them right into the freezer. After the dumplings harden, transfer them to freezer bags. When you are ready to cook the dumplings, stick them directly onto the pan. There is no need to defrost the dumplings.
Typically, I like cooking pan-fried dumplings in my cast iron pan because it blisters the dumpling wrapper the best, creating an extra crispy skin. However, if you use thinner wrappers, the dumplings won’t lift off from the pan too well, so you’ll get a lot of dumpling wrapper stuck onto the pan. For these dumplings, I used wrappers of medium thickness and used a non-stick pan to cook the dumplings.
