In a large bowl, whisk together the glutinous rice flour, GF flour blend, sea salt, and xanthan gum. Make a well in the center.
Add the eggs, oil, and a tablespoon of water to the well. Stir to combine. The mixture should look ragged and clumpy.
Knead the dough in the bowl, adding a teaspoon of water at a time and continuing to knead until the dough comes together into a ball. There should be no more pockets of dry flour, and the dough should be mostly smooth. The dough should be a bit sticky but not too sticky that it’s sticking to your hand.
Divide the dough into two balls, wrap with cling wrap and press down to form a disc. Refrigerate for 30 minutes or up to two days in advance. Bring to room temperature before rolling out.
Dust a work surface liberally with cornstarch or tapioca starch. Roll out each disc, one at a time, thinly. You should be able to see your hand, or the print on your work surface through the dough. Cut the dough into squares between 3”-4”. You can cut the dough into even squares with a pizza cutter, or you can use a square biscuit cutter.
Stack the wrappers, sprinkling each with cornstarch or tapioca starch before stacking so they don’t stick together. Wrap the wrapper stack with a lightly damp paper towel so the wrappers don’t dry out before stuffing and cooking.
Notes
The total serving size is approximate and will vary based on how big you cut your wrappers.
To Store: The dough will keep in the fridge for up to 2 days. Let it come to room temperature before rolling and filling.
To Freeze: Layer the wrappers with cornstarch/tapioca starch or parchment paper, wrap in plastic wrap and store in an airtight container or ziplock bag. They'll keep in the freezer for up to 2 months. Let them thaw in the fridge before using.
