Briefly knead again, then divide into four equal portions using a dough cutter. Each portion should come out to 175–180g.Repeat the following steps for each of them. Reference pictures above! Shape the dough into an oval so it comes out long and narrow once you flatten it.
Using a rolling pin (recommended) or your hands, flatten it enough to fit through your pasta maker on the widest setting.
Feed it through the pasta maker's sheeting rollers on the widest setting, then fold it over once and feed it through again.
Decrease the thickness to your desired level and feed the dough sheet through one more time.My pasta maker ranges from 1 (thickest) to 9 (thinnest). I've found that 2 is the perfect thickness for ramen noodles. Lightly dust the dough sheet in corn starch.
Feed the dough sheet through the pasta maker's spaghetti cutter. Make sure the noodles land safely underneath, or have someone help you catch them.
If you are storing the noodles for later, dust them again with starch to prevent them from sticking together, then put in a freezer bag (or similar). Keep in the fridge uncooked for up to 5 days. When you take them out for cooking, gently untangle them again to prevent clumping up in the water.
