Sift the millet flour and bread flour together.
Slowly incorporate water into the flour mix massaging the water into the flour to ensure the water hydrates the flour mix. Continue until the dough comes together into one cohesive dough.
Knead the dough for 5 minutes to get a soft and supple dough.
Cover the dough and let it rest at room temperature for at least 30 minutes. This allows the gluten to relax.
Generally dust the surface of your work station with the potato starch. Divide the dough into two and roll each out into a thin sheet. If you are using a pasta roller, just roll it out thin enough to pass through the thickest setting of the pasta roller. If you are going to cut by hand, roll it out to as thin as 1/2 milimeter.
