Juicy Steamed Dumplings

Why I Love This Recipe
My son helps with rolling out the dough and my daughter enjoys squeezing the dumplings together. This is a great item for their lunch or as a snack. We all enjoy making it together.
My notes on this recipe read:
We needed almost another cup of water to make the dough. Also, this much dough was too much for the amount of pork I had done. (3 pork chops) I used it all but the dumpling wrappers were quite thick.
Ingredients You'll Need
1 lb (500 g) lean boneless pork, cooked
4 tsp soy sauce
1/2 tsp rice wine
1/2 tsp fresh ginger, chopped
1 tsp salt
1/2 tsp sugar
1/2c (4 oz) (125 ml) sesame oil
4 1/2c (500 g) flour, sifted
1c cold water
Directions
Wrappers:
Add flour to water gradually and mix into dough. Let the dough rest while you prepare the filling.
Filling:
Mince the pork. Mix the pork, soy sauce, rice wine, ginger, salt and sugar.
Stir in the sesame oil.
Cut the dough into 1/2 oz balls.
Flatten and roll into a 3" piece with a raised middle. (To do this, roll from the middle out.)
Add 1 to 1 1/2 tsp filling on top of the wrapper.
Pinch the edges of the wrapper to seal. (You may use a little water to help close the edges.)
Steam for 5 minutes over high heat.
