Set aside a bowl with tapioca starch to use for sprinkling when the dough is sticky.
Measure dry ingredients in food processor or electric mixer.
Turn on to briefly combine. Add boiled water with motor running and mix until combined.
Add egg and continue mixing until smooth dough is formed.
Turn dough onto counter and lightly sprinkle with tapioca starch. Cut into 4 pieces. Work with one piece at a time keeping the remaining pieces of dough covered with a dry cloth.
ROLLING PASTA WITH A HAND-CRANK MACHINE
Set pasta machine to its' widest setting.
Flatten one piece of pasta dough with your hands or a rolling pin. Feed the flattened dough through the roller as you turn the crank.
Place the dough lengthwise in front of you. Fold each side over in thirds. Repeat the process 3-4 times until the dough is smooth and the width of the pasta roller. This is the important step where you are trying to make a single piece of smooth dough with even edges that are the width of your machine. Keep rolling it until you have fairly smooth edges, even if it takes 10 times.
Adjust the pasta roller to the next setting and feed the dough through again. Repeat this process, adjusting the roller to a narrower setting each time until you reach the desired thickness for your pasta.*
When a piece is too long to manage, lay it on the counter and cut it in half.
Once your pasta is the desired thickness it can be cut into any shape. Repeat this process with the remaining portions of dough. Shape as desired.
Many hand-crank machines have a setting for fettuccini so that's a great place to start.
As each piece of pasta is cut into fettuccini carefully twist and twirl into a loose nest. Lay on a baking sheet to dry slightly as you repeat the process with each piece of dough.
If not using within 30 minutes cover and refrigerate. Cook within 3 days.
COOKING FRESH GLUTEN FREE PASTA
Cook fresh pasta in plenty of boiling water for 3-5 minutes depending on the thickness. **
Start checking the pasta after the first few minutes to avoid over cooking. Keep notes so you can perfect the thickness and cooking time for perfect pasta every time.
Drain, rinse briefly to stop cooking process. Toss with hot pasta sauce and serve immediately.
Notes
*The number of settings each roller has varies by manufacturer. My machine starts at 1 (the widest setting) and has 7 settings, 7 being the thinnest. Some machines are the opposite and may have a different number of settings. Always start with the widest setting.Personal note: On my machine setting 4 is a bit too thick for my taste. Setting 5 and 6 takes more practice but is better for ravioli and tortellini where you're biting through 2 thicknesses of the dough each time. I'm still practising.**Fresh pasta cooks much faster than dried pasta. Don't skimp on the water and pay attention to the clock.
