1/2 cup (75g) bamboo shoots, minced

1/2 lb (225g) raw shrimp, peeled, deveined, and coarsely chopped
1/2 lb (225g) ground pork
3 stalks green onions, minced
1/4 cup (55g) ginger root, minced
1 cup (142g) water chestnuts, minced
1 tsp (5g) salt
3 tbsp (40g) sesame oil
2 tbsp (16g) corn starch
dough: (double this for the amount of filling, but easier to make it in 2 batches - or just halve the filling recipe)
2 cups (250g) all-purpose flour
1/2 cup (113g) warm water
flour for worksurface
dipping sauce:
2 parts soy sauce
1 part vinegar (red wine or black)
a few drops of sesame oil
chili garlic paste (optional)
minced ginger (optional)
minced garlic (optional)
minced green onion (optional)
sugar (optional)
Combine all filling ingredients in a large mixing bowl and mix thoroughly (I mix by clean hand). Cover and refrigerate until ready to use (up to a day, but preferably within an hour or two).
Make the dough, Method 1: Place the flour in the work bowl of a food processor with the dough blade. Run the processor and pour the warm water in until incorporated. Pour the contents into a sturdy bowl or onto a work surface and knead until uniform and smooth. The dough should be firm and silky to the touch and not sticky.[Note: it’s better to have a moist dough and have to incorporate more flour than to have a dry and pilling dough and have to incorporate more water).
Make the dough, Method 2 (my mom’s instructions): In a large bowl mix flour with 1/4 cup of water and stir until water is absorbed. Continue adding water one teaspoon at a time and mixing thoroughly until dough pulls away from sides of bowl. We want a firm dough that is barely sticky to the touch.
Both dough methods: Knead the dough about twenty strokes then cover with a damp towel for 15 minutes. Take the dough and form a flattened dome. Cut into strips about 1 1/2 to 2 inches wide. Shape the strips into rounded long cylinders. On a floured surface, cut the strips into 3/4 inch pieces. Press palm down on each piece to form a flat circle (you can shape the corners in with your fingers). With a rolling pin, roll out a circular wrapper from each flat disc. Take care not to roll out too thin or the dumplings will break during cooking - about 1/16th inch. Leave the centers slightly thicker than the edges. Place a tablespoon of filling in the center of each wrapper and fold the dough in half, pleating the edges along one side. Keep all unused dough under damp cloth.
To boil: Bring a large pot of water to a boil and add dumplings to pot. Boil the dumplings until they float.
To steam: Place dumplings on a single layer of napa cabbage leaves or on a well-greased surface in a steamer basket with lid. Steam covered for about 6 minutes.
To pan fry (potstickers): Place dumplings in a frying pan with 2-3 tbsp of vegetable oil. Heat on high and fry for a few minutes until bottoms are golden. Add 1/2 cup water and cover. Cook until the water has boiled away and then uncover and reduce heat to medium or medium low. Let the dumplings cook for another 2 minutes then remove from heat and serve.
To freeze: Assemble dumplings on a baking sheet so they are not touching. It helps to rub the base of the dumpling in a little flour before setting on the baking sheet for ease of release. Freeze for 20-30 minutes until dumplings are no longer soft. Place in ziploc bag and freeze for up to a couple of months. Prepare per the above instructions, but allow extra time to ensure the filling is thoroughly cooked.
To serve: Serve dumplings or potstickers hot with your choice of dipping sauce combinations.
The bag is completely chocolate and filled with homemade poundcake, chocolate mousse, and fresh berries. Absolutely delicious!!!
