For the dough, mix the flour and salt. Add water and egg white and combine with your hands. Knead the dough until smooth. Cover and let rest for 20 minutes. Knead the dough again then roll into a log. Cut that into 2 pieces and then roll out the small logs again. Cut into 6 pieces (about 12 total). Roll out each piece to a round dumpling wrapper, keeping the surface dusted with flour to avoid sticking.
