After the resting period, remove the dough from the bowl and place it on a lightly floured surface. Divide the dough into smaller portions, about the size of golf balls.
Take one portion of the dough and roll it into a small ball between your palms. Flatten the ball with the palm of your hand.
Using a rolling pin, roll out the flattened dough into a thin circle, approximately 3-4 inches in diameter. Rotate the dough occasionally to ensure even thickness.
Place a spoonful of the prepared dumpling filling in the center of the dough circle. Be careful not to overfill, as this can make it difficult to seal the dumplings properly.
Fold the dough in half, enclosing the filling, and pinch the edges together to seal. Create pleats along the sealed edge for added aesthetics, if desired.
Repeat the process with the remaining portions of dough and filling until you have shaped all the dumplings.
