The minimum you need to make your own noodles is:
- a large, flat surface
- a rolling pin
- a good knife
That's it?!?!? Yes: because all you need to do is combine flour and eggs (and maybe some salt, and maybe a little oil), knead the dough, roll it out, and cut it.
But to be honest, I use my KitchenAid mixer with dough hook and pasta roller/cutter attachment. The dough hook is for mixing the eggs into the flour. I knead it by hand. Then I use the rollers to thin it and the cutters if I'm making something like fettuccine, since it is a lot easier, faster, and more even, and requires much less counter space and time. If I want to make other shapes, I thin it with the rollers and cut it using various cutting wheels.
And then again, Marcella Hazan says that some kinds of noodles are actually better store-bought!
