Establish the Dough Matrix
Sift the flour and salt into a large bowl. Gradually pour in the water while stirring with chopsticks or a fork until a shaggy dough forms. Turn the mixture onto a clean surface and knead vigorously for 6–8 minutes until a smooth, firm, and elastic ball forms. Wrap tightly in plastic wrap and leave to rest at room temperature.
Kneading develops the gluten network required to stretch the wrappers paper-thin without breaking. Resting relaxes these gluten bonds so the dough doesn't snap back when rolled.
The dough should feel smooth like an earlobe and lose its surface stickiness entirely.
