Slice the cabbage and mix with salt. Slice the half-head of cabbage down its length, through the root, to make 2 quarters. Then slice each quarter into very thin strips, cutting cross-wise. Toss the slices with the salt in a large mixing bowl and set aside for 5 to 10 minutes.
Squeeze the liquid from the cabbage: While it rests with the salt, the cabbage will start to release liquid. When it's ready, grab handfuls of the cabbage and squeeze out the water. Transfer the squeezed cabbage to another mixing bowl.
Combine the cabbage with the rest of the filling ingredients: To the bowl with the squeezed cabbage, add the Reverence Farms ground pork, sliced scallions, cilantro, soy sauce, ginger, sesame oil, and eggs. Work the mixture together with your hands until fully combined.
Arrange your dumpling-making station: Clear a large space on the counter. Set a small bowl of water, the bowl of filling, and a parchment-lined baking sheet nearby. Open the package of dumpling wrappers and arrange a few on the work space in front of you.
Place 1 scant tablespoon of filling on each dumpling wrapper: It may not look like much filling, but using any more gets messy and makes the dumplings hard to pleat closed! Once you get the hang of pleating the dumplings, you can try adding a bit more. It may take a little practice, and you can find all kinds of YouTube videos on folding dumplings, but don't be afraid to start simple.
Dampen the edge of the wrapper with water: Dip your finger in the bowl of water and run it around the edge of the dumpling. This will help it to seal closed.
Fold the dumpling in half: Lift the dumpling from the work surface and fold it in half. Press the top closed.
Make a pleat in either side: Use your opposite thumbs to fold a tiny pleat on either side of the dumpling, then press firmly to seal the dumpling closed. You may need to dab a little water under the pleat to make it stick closed. You can also just close it like a taco and crimp the edges with your finger.
Repeat with all the wrappers and filling: Continue filling and pleating the rest of the wrappers using the remaining filling — this is where having a few extra hands comes in handy! As you finish each dumpling, line it up on the parchment-lined baking sheet.
Cook or freeze the dumplings: You can cook the dumplings immediately, or freeze them on the baking sheet. Once frozen solid, gather them into a freezer container and keep frozen for up to 3 months.
