Place the chopped napa cabbage in a bowl and sprinkle lightly with salt. Toss and let it sit for about 10 minutes, then squeeze out as much liquid as you can and set aside. This helps keep the filling flavorful without watering it down.
In a medium bowl, combine the ground pork, drained napa cabbage, green onions, ginger, garlic, soy sauce, Shaoxing wine, sesame oil, sugar, black pepper, and cornstarch. Mix until everything is evenly combined. The mixture will stay raw—it cooks gently as the dish steams.
Divide the pork mixture into four equal portions so the layers stay even.
Lightly oil two ramekins. Place a wonton wrapper in the bottom of each ramekin, pressing it gently against the sides. Drizzle 1–2 tablespoons of chicken broth over the wrapper.
Add ¼ of the pork mixture to each ramekin and spread it into an even layer. Top with another wonton wrapper and drizzle with a little more broth.
Add another ¼ of the pork mixture, then top with a final wonton wrapper. Finish with 2–3 tablespoons of chicken broth, making sure you can see liquid around the edges.
Place the filled ramekins into a deep skillet. Carefully add water to the skillet so it comes about halfway up the sides of the ramekins. Cover with a lid.
Bring the water to a gentle simmer and steam for 15–20 minutes, until the pork is fully cooked and the wonton wrappers are tender.
Carefully remove the ramekins from the skillet. Top with chili crisp and sliced green scallions and serve hot, making sure to spoon up plenty of that broth at the bottom.
