1Add 300g of all-purpose flour to a bowl on a kitchen scale.
2Add a pinch of salt for flavor.
3Add 150g of just-boiled water to the flour and salt mixture.
4Use a spatula to mix the ingredients until a shaggy dough forms.
5Knead the dough in the bowl until a rough dough ball forms, then transfer it to a clean counter.
6Knead the dough for a couple of minutes until it's smooth-ish.
7Cover the dough ball with a bowl to rest for at least 30 minutes, and up to 2 hours.
8Cut the dough in half.
9Roll the dough into a long log.
10Eyeball the middle point of the log and cut it in half. Keep dividing the pieces in half until you have 16 pieces from each half of the original dough.
11Pinch each piece of dough between your thumb and index finger while rotating to form a round shape.
12Put a round piece of dough on your counter, add a little bit of flour, and flatten it with your palm. Flip it over so both sides are covered in flour.
13Place the rolling pin over the center of the dough, apply pressure, and roll towards yourself.
14Rotate the wrapper about 15 degrees, place the rolling pin back on the center, and roll towards yourself. Repeat this motion until the dumpling wrapper is about 3 inches in diameter.
15Add the dumpling filling and then pleat it to close the dumpling.
