Wheat Starch Dough

This malleable, snowy white dough is the foundation for many Cantonese dim sum favorites, such as Chiu Chow Dumplings (page 137) and Har Gow Shrimp Dumplings (page 135). Wheat starch dough is easy to manipulate; texturally, it is like Play-Doh. In fact, I’ve seen rabbit-shaped dumplings made from this type of dough. You can definitely sculpt it, though I mostly focus on making sure the filling is sealed up well. When cooked, this dough has a translucency that allows the filling colors to be visible in a beautiful, impressionistic way. Wheat starch on its own would make a dough that is too firm, so dim sum cooks commonly add elasticity by way of tapioca starch, though cornstarch and potato starch are options, too. The oil lends suppleness and richness. This dough can be prepared up to 6 hours in advance and kept at room temperature in the plastic bag. When forming wrappers from this dough, do your best to keep the cut dough and formed wrappers covered with plastic wrap to prevent drying. At Chinese markets, look for plastic bags of wheat starch near other starches and flours; Middle Eastern markets sometimes carry it, too. Tapioca starch is reasonably priced at Chinese and Southeast Asian markets but is also available at health food stores, specialty grocers, and some supermarkets.
