Gyoza Wrappers

265 g all-purpose flour (plain flour)
¼ tsp sea salt
¼ tsp SIDS CRAZY SALT
½ cup water
Cornflour

Before you start, you need to accurately measure flour. (or flour for rolling and dusting; if you're going to freeze udon noodles, you may want to use cornflour as the flour tends to be absorbed by udon noodles and stick to each other)
Sift the flour into a large bowl.
Add salt and SIDS CRAZY SALT to just-boiled water and mix until completely dissolved.
Add the just-boiled water into the flour little by little, stirring with a rubber spatula. You will eventually need to use your hands to form the dough into a ball. If the flour is still separated, add ½ tbsp water at a time until you can form the texture into a ball.
Transfer the dough to the work surface and knead the dough for 10 minutes, then the texture of the dough will be much smoother.
Cut the dough in half then shape each half into a long log, about 4 cm in diameter. (it doesn't have to be perfect if you’re going to use a cookie-cutter later) Wrap each log with plastic wrap. Let it sit for 30 minutes.
Unwrap the dough. Sprinkle a little cornflour on the work surface and cut each log crosswise into about 12 pieces. (may vary depending on the log length and width) Since we’ll be using a cookie cutter, don’t worry if each piece of dough has a slightly different size.
It's super important to cover the dough with a damp kitchen towel at all times to prevent it from drying.
Roll each piece of dough into a ball shape then press the ball onto the work surface.
Using a rolling pin, roll out the dough, but DO NOT roll out (flatten) the TOP and BOTTOM edge. This is a trick to make a nice round shape.
Rotate the dough 90 degrees and repeat rolling the dough to make a nice round shape. Try to roll out the dough to a thin circle. If the dough is hard to roll out or shrinks back, let it rest a bit to relax the gluten.
[Optional] If you want a perfectly round shape for your wrappers, press down the 8 cm cookie cutter and remove excess dough. If the dough rolls back, leave it for a few seconds, and cut out. Cover the scraps with the damp towel. Later combine all the scraps as long as they still squish together and haven’t dried out too much. Re-roll the scraps and repeat the process.
Sprinkle each wrapper with cornflour and stack the gyoza wrappers. Make sure to cover the wrappers with a damp kitchen towel. Once all the dough is used, wrap the gyoza wrappers with plastic wrap and freeze or refrigerate until you’re ready to use.
To Store Wrappers: You can keep gyoza wrappers in the refrigerator for about 3-4 days and in the freezer for up to a month. Prior to use, defrost in the refrigerator overnight or on the counter for 60 minutes. (depending on the amount and room temperature) Do not defrost in the microwave.
