Clear Siu Mai Wrapper Dough Recipe

Ingredients:

• 250g wheat starch

• 50g cornstarch

• 350ml boiling water

• 10g lard or cooking oil (optional, for added elasticity)

Step-by-Step Instructions

1. Mix Dry Ingredients

• In a large bowl, combine 250g wheat starch and 50g cornstarch.

  Scientific Insight: Wheat starch gives the dough its signature translucent appearance once steamed, while cornstarch adds smoothness and a bit of elasticity to the dough, making it easier to work with and preventing it from tearing.

2. Add Boiling Water

• Slowly pour 350ml of boiling water into the starch mixture while stirring constantly with a spoon or spatula.

  Why Boiling Water?: The high temperature of boiling water partially cooks the starches, which gelatinizes them. This makes the dough more pliable and easier to shape. It also contributes to the smooth, clear texture of the final wrapper.

3. Knead the Dough

• Once the dough is cool enough to handle, transfer it to a clean surface and knead it for about 5-10 minutes until it becomes smooth and soft.

  Tips for Texture:

  • If the dough feels too dry, add a little more hot water (not cold) to hydrate it.

  • If the dough is too sticky, add a small amount of wheat starch to absorb the excess moisture.

  Scientific Insight: Kneading helps distribute the water evenly, developing the structure of the dough. It also allows the starches to absorb water, creating a smoother and stretchier dough.

4. Optional: Add Lard or Oil

• For a smoother and more elastic texture, knead in 10g of lard or cooking oil.

  Why Add Fat?: Lard or oil helps lubricate the dough, making it more flexible and less prone to cracking. This also makes the final wrappers softer and easier to fold around fillings.

5. Rest the Dough

• Cover the dough with a damp cloth and let it rest for 15-20 minutes.

  Scientific Insight: Resting allows the starch molecules to fully absorb the water and relax, making the dough easier to roll out and shape without tearing. This step is essential for achieving a pliable, workable dough.

6. Roll Out and Shape

• After resting, roll the dough thinly on a flat surface (about 2mm thick).

• Cut the dough into small circles (approximately 3 inches in diameter) for your siu mai wrappers.

  Tips: Keep the dough covered with a damp cloth while working with portions, as it can dry out quickly.

  Why Thin Dough?: Thin dough allows the steam to cook the wrapper evenly and ensures the filling stands out. The transparency is a hallmark of clear dumpling wrappers.

Scientific Overview

• Wheat starch is the primary ingredient responsible for the translucent, almost glass-like appearance of the wrappers.

• Cornstarch improves the dough's elasticity and smoothness, making it more manageable when rolling and shaping.

• Boiling water gelatinizes the starches, which is essential for achieving a smooth, stretchy, and cohesive dough.

• Resting the dough ensures that the starches fully hydrate, resulting in a dough that is easier to roll and work with.

By following these steps, you’ll be able to create perfectly thin, translucent, and elastic wrappers for your siu mai dumplings.
