Sift the flours into a large mixing bowl and add the salt.
Pour the hot water into the mixing bowl and mix with the flour until a dough forms.
Transfer the dough to a clean dry surface. Add a little flour to the surface if your dough is too sticky, but be sparing. Too much flour= dry dough.
Knead for 10 minutes until smooth.
Wrap it with plastic kitchen wrap and leave to rest for 30 minutes at room temperature.
Once rested, cut the dough in half and roll each piece into even cylinders. (If doubling the recipe, cut into 4. If tripling the recipe, cut into 8.) Wrap any that aren't being used straight away to stop them from drying out.
Cut cylinder of dough in half, then half again and continue to half until you have 16 pieces.
Roll each piece into a ball.
Now dust your surface with flour and push one ball of dough flat down using the palm of your hand.Roll it flat using a rolling pin, turn and flip from time to time to keep it at an even thickness and prevent it from sticking to the surface. Roll it as thin as you can without breaking it.
Pick up the wrapper and use your fingers to pinch around the edges, making the edges even thinner and neatening the circle shape.
Generously rub flour on the top and bottom of the wrapper ready for stacking.
Repeat with the rest of the dough and store the completed wrappers in an airtight container to stop them from drying out.
Use the wrappers with your favorite gyoza fillings. (See in the post for how to shape with filling and check out my pork gyoza recipe for how cook the perfect gyoza with a crispy base.) Enjoy!
