What type of flour is used to make the translucent skin of har gow dumplings?

The translucent skin of har gow dumplings is made primarily with wheat starch. Har gow, also called ha gow or xia jiao, is a Cantonese shrimp dumpling served in a bamboo steamer as dim sum.

Unlike ordinary dumpling wrappers made from wheat flour, wheat starch produces a smooth, translucent skin when mixed with boiling water and steamed. Recipes commonly add tapioca starch, potato starch, or another starch to improve elasticity and help the wrapper hold its shape.

The skin must balance two difficult qualities: it should be thin enough to show the shrimp inside, yet strong enough to survive pleating, steaming, and lifting with chopsticks. This is why har gow is often described as a test of a dim sum chef’s skill.

Cornstarch, rice flour, and tapioca starch can appear in recipes, but they are not the principal answer for the classic wrapper. Tapioca or potato starch is usually a supporting ingredient, helping create flexibility rather than replacing wheat starch entirely.
