Step 1

Combine the tapioca starch, sweet rice flour, millet flour, quinoa flour, xanthan gum, and salt in a large bowl. Whisk to combine. Then make a well in the center of the flour mixture.

Step 2

Add the yolks, eggs, and water. Stir with a spoon to mix and incorporate all of the flour. Switch to using your hands and mix/knead until the dough is a uniform, mostly-smooth texture. (The dough doesn't have to be perfectly smooth on the outside. That will happen naturally when you roll the dough.)

Step 3

Divide the dough into eight pieces. Work with one piece at a time. Keep the remaining pieces of dough in an airtight container or ziptop bag to keep them from drying out until you're ready to work with each one.

Step 4

Dust your work surface lightly with sweet rice flour. Roll the first piece of dough into a ball between the palms of your hand. Then use a rolling pin to roll the dough out on the prepared surface to about 8 to 10 inches square, until the dough is very thin.(The edges of your rolled-out sheet of pasta dough may be jagged. Use a knife or pizza cutter to trim them clean, if desired. Rotate and/or flip the dough a few times while rolling, and dust lightly with additional sweet rice flour if needed, to prevent sticking. Once rolled out, the dough should be thin enough to see the work surface underneath, about 1/16 inch or less than the thickness of a dime.)

Step 5

Cut the dough into the desired shape (e.g., strips for fettuccine, 2-inch squores for tortellini).

Step 6

Cook the pasta in salted, boiling water for about 4–5 minutes. (For filled pastas, once they have begun to float, cook for 4 more minutes.)
