Ingredients
Dumpling Skins:
3 cups all-purpose flour
1 1/4 cups cold water (as needed)
1/4 tsp salt
Alternatively, dumpling skins can be bought from an Asian grocery.
Filling:
1 cup ground pork
1 TB soy sauce
1 tsp salt
1 TB Chinese rice wine or dry sherry
1/4 tsp freshly ground white pepper, or to taste
3 TB sesame oil
1/2 green onion, finely minced
1 1/2 cups finely shredded Napa cabbage
2 slices fresh ginger, finely minced
1 clove garlic, peeled and finely minced
Method
Stir the salt into the flour. Slowly stir in the cold water, adding as much as is necessary to form a smooth dough. Knead the dough into a smooth ball. Cover the dough and let it rest for at least 30 minutes.
While the dough is resting, prepare the filling ingredients. Add the soy sauce, salt, rice wine and white pepper to the meat, stirring in only one direction. Add the remaining ingredients and mix well.
To make the dumpling dough, knead the dough until it forms a smooth ball. Divide the dough into 60 pieces. Roll each piece out into a circle about 3-inches in diameter.
Place a small portion (about 1 level tablespoon) of the filling into the middle of each wrapper. Wet the edges of the dumpling with water. Fold the dough over the filling into a half moon shape and pinch the edges to seal. Continue with the remainder of the dumplings.
To cook, bring a large pot of water to a boil. Add half the dumplings, giving them a gentle stir so they don't stick together. Bring the water to a boil, and add 1/2 cup of cold water. Cover and repeat.
When the dumplings come to a boil for a third time, they are ready. Drain and remove. If desired, they can be pan-fried at this point.
