On a large flat surface suitable for kneading dough, make a pile out of your flour.
Create a well in the center of the flour and add your other ingredients.
Using a fork, stir the ingredients to work them together, gradually scraping at the sides of the well to incorporate the flour.
Once it's too thick for the fork, switch to mixing and kneading by hand.
Knead and knead until the dough is nicely worked. To check, press a thumb into the dough. If it mostly springs back, you're good.
Cover the dough and let it rest for at least 30 minutes.
Divide the dough into four or so small portions.
Feed a portion of dough into the rollers to press and thin it out. Fold it in half and re-feed it through, to continue kneading. Once the dough becomes pliable, narrow the roller gradually until it reaches whatever your setting is for spaghetti.
Once your dough portions have all been flattened, switch to the spaghetti cutter. Feed them through to cut your spaghetti.
To cook, simply add to boiling water in batches, cooking for about 1-2 minutes or to your preference for texture.
