When we were children, shrimp dumplings were our favorite dim sum dish. The classic filling is shrimp and bamboo shoots. The dough is not difficult to make, but it is very important that the water be boiling hot. If it is not hot enough, the wheat starch will not cook and the dough will not work. Wheat starch _(dung fun)_is only available in Chinatown; regular white flour is not a substitute.
The tortilla press used here is excellent for making the dough into thin, uniform rounds, but you can also make the dumplings by hand: Roll the dough into scant 1-inch balls. Place one ball between your lightly floured hands and press to form a circle. Press the dough evenly with your fingertips to make it as thin as possible, about 3 inches in diameter and a scant 1/8-inch thick.
