Wash the cabbage by gently pulling apart the leaves and rinsing each layer.
Arrange the cabbage leaves horizontally onto a cutting board and cut into 2-inch-long, ¼-inch-thick pieces. Place into a large bowl.
Sprinkle 1 tablespoon of kosher salt over the cabbage, mix well, and let sit for 10 minutes.
Squeeze the cabbage over a large colander to wring out excess moisture and catch any pieces that fall out. Set aside.
Add the pork, shrimp, Chinese chives, green onions, cabbage, and ginger to a large mixing bowl and mix well.
Add soy sauce, sesame oil, white pepper, and 2 teaspoons salt to the mixing bowl, and mix well.
Lay plastic wrap onto a clean surface for your wrapping station and sprinkle a small amount of flour across the entire surface. Prepare 3 half-sheet baking pans by sprinkling flour onto each and setting aside.
Set up your wrapping station by arranging the dumpling filling, 1 cup of water, and the room temperature dumpling wrappers in the middle of your working surface.
Place one wrapper completely flat in the palm of your hand. Place a minimum of 2 teaspoons of filling in the center of the wrapper.
Dip your pinky or index finger into the water and circle the edge of the wrapper.
Fold the wrapper in half and pinch the sides in, forming a half moon with triangles on each end to seal.
Note: For a visual guide on sealing dumplings, see our Cooking with Cosori video.
Place the completed dumplings onto the floured baking sheets, continuing with the remaining filling and wrappers.
To Cook as Dumplings - Step 1
Fill a large pot halfway with water and bring to a boil.
Add 15 dumplings at a time to the water. Allow the water to come back to a boil, then lower heat to a medium simmer.
Cook the dumplings until done, about 8 minutes.
Remove the dumplings from the water when done and place on a clean plate.
Serve immediately with a side of soy sauce and sambal to enjoy as dumplings.
To Cook as Potstickers - Step 1
Select the Preheat function on the Cosori Air Fryer, set temperature to 380°F, and press Start/Pause.
Spray the preheated inner air fryer basket and dumplings with oil spray.
Place 12 dumplings (frozen or cooked) into the inner air fryer basket. You will need to work in batches.
Set temperature to 380°F and time to 10 minutes, press Shake, then press Start/Pause.
Flip the potstickers over and spray with oil spray halfway through cooking. The Shake Reminder will let you know when.
Remove the potstickers from the air fryer when done.
Repeat the cooking process with the remaining dumplings.
Serve immediately with a side of soy sauce, sambal, black vinegar, and fresh ginger.
Note: Freeze the remaining dumplings or potstickers on baking sheets overnight, then transfer into an airtight bag or container to store. The frozen dumplings or potstickers have a shelf life of 1 month and are best eaten within 3 weeks of freezing.
