This comforting pork wonton soup features tender homemade wontons filled with savory pork, bok choy, sesame oil, soy sauce, and Shaoxing wine. Serve them in a light chicken broth with scallions for a cozy Chinese-style soup that is perfect for make-ahead meals.
Rinse the baby bok choy well, especially near the stems where grit can hide. Bring a large pot of water to a boil, add the greens, and blanch for 60-90 seconds, just until wilted. Drain, then rinse under cold water to stop the cooking.
Squeeze the cooled bok choy firmly to remove as much excess water as possible. Finely chop it by hand, or pulse it in small batches in a food processor until very fine.
In a mixing bowl, combine the chopped bok choy, ground pork, 1/2 tbsp sesame oil, white pepper, soy sauce, salt, and Shaoxing wine. Stir in one direction until the filling becomes sticky and cohesive, almost like a paste.
Set out a small bowl of water. Place one wonton wrapper on your work surface, add about 2 tsp filling to the center, and lightly moisten the edges with water. Fold the wrapper in half and press out any air pockets while sealing the edges.
To shape each wonton, bring the two lower corners together and seal them with a small dab of water. Place finished wontons on a parchment-lined baking sheet, keeping them from touching.
Cook 1 or 2 wontons in boiling water to test the seasoning. Taste and adjust the remaining filling with more soy sauce, Shaoxing wine, sesame oil, salt, or white pepper if needed, then continue wrapping the rest.
Cook the wontons right away or freeze them immediately. To freeze, place the tray in the freezer until the wontons are solid, at least 6 hours or overnight, then transfer them to freezer bags and store for up to 3 months.
For the soup, bring the chicken stock to a gentle simmer. Stir in the remaining 2 tbsp sesame oil, then season with salt and white pepper to taste.
Bring a separate pot of water to a boil for the wontons. Stir the water to create movement, then add the wontons one at a time so they do not stick to the bottom. Once they float, cook for another 1-2 minutes, or until the filling is fully cooked.
Lift the wontons out with a slotted spoon and divide them among serving bowls. Ladle the hot seasoned broth over the top, garnish with sliced scallion, and serve immediately.
Squeeze the bok choy very dry so the filling stays firm and does not make the wrappers soggy. If Shaoxing wine is unavailable, use dry sherry or omit it. Cook wontons in plain water instead of directly in the broth to keep the soup clear. Frozen wontons can be cooked straight from the freezer; add 1-2 extra minutes once they float.
