Chinese dumplings...there are the boiled kind which is made often. I don't know much about the chili soup you're talking about though.
Dumpling Wrappers/Skins
1 lb ground pork
1 lb garlic chives
soy sauce
flour
Beaten Egg
You'll just want to chop up the garlic chives into 1 cm long pieces and mix them with the ground pork and the soy sauce and the flour.
The soy sauce adds salt and enhances the flavor of the pork and the chive; the flour serves as a thickener so that the little dumplings inside the wrappers doesn't fall apart when it comes out.
From that point you can be as creative as you want, sometimes I add sugar and rice wine, sometimes I'll add more american/western herbs and spices. Maybe a little garlic chili sauce would make it special?
Take a beaten egg and using your finger, outline the outer edge of one half of a wrapper with the egg. Fill the wrapper with just a small amount of filling, maybe a tablespoon, then fold over and press the two sides together. Make sure all the air has been pressed out.
So thats one done. When you have all you want done you can boil them on the spot, fry them on the spot, or freeze them for use later.
I know this was a little bit thrown together! But I hope this helps.
