I started with a pile of flour on the counter, about 2 cups. I made a well in the center of the pile of flour, and dropped in one egg yolk.
I broke the yolk and started mixing it with the flour, then added water and kept bringing in more of the flour a little at a time until al the flour was incorporated and I had a nice stiff dough.
I floured the counter lightly, and kneaded the dough until it was smooth and then wrapped it up and let it sit while I worked on other things.
I floured the counter again and rolled the dough out to an reasonable thickness, then rolled it up and cut it into strips.
I unrolled the strips, dusted them with flour to keep them from sticking, and left the on the countertop until I was ready to cook.
For the sauce, I made a light creamy mushroom sauce.
These were darned good noodles - the kind of noodles that don't need a whole lot of sauce.
