Add ground pork, oyster sauce, light soy sauce, dark soy sauce, sesame oil, sugar, water, white pepper, sichuan peppercorn, salt, chopped garlic chives, grated ginger, and scallion to a medium mixing bowl.
Using a pair of chopsticks or a fork, whisk vigorously in one direction until the the ingredients are not only combined, but the texture of the meat changes and looks almost like a paste.
To create your dumpling making station, set up a sheet of parchment paper, a small bowl of water, the bowl of filling with either a spoon or pair of chopsticks, and wrappers. If using store bought wrappers, remember to cover wrappers with a damp paper towel.
Wet the outer rim of a wrapper with warm water using your finger. Then either using chopsticks or a spoon, add approximately 1 tablespoon of filling to the middle of the wrapper and seal, making sure to remove air pockets. Transfer prepared dumpling onto a sheet of parchment paper until ready to cook. Repeat until all of the filling or all of the wrappers have been used.
Cook your dumplings in preferred method:
Steam for 8-10 minutes. Or
Boil for 8-10 minutes. Or
Or pan fry (potstickers). To pan fry, coat a non-stick pan with a generous glug of vegetable oil. Heat. Place dumplings in a circle to fill the pan. Fry on medium heat until the bottoms are browned, 2-3 minutes. Then fill with ½ cup water and cover. Cook for 6-7 minutes. Uncover and finish cooking until all the water has cooked off.
Dipping Sauce
Combine all dipping sauce ingredients and stir. Adjust seasoning to personal preference. Spoon over dumplings or dip dumplings directly into bowl. Optionally serve with more cilantro and chili oil/crisp.
