I watched a friends Italian Momma make her pasta one day. (She did it all by hand) I make it following her directions but I use the Food Processor to mix and knead.
1 egg for each cup of flour( plus an extra egg for every 3 cups of flour, ie. 3 cups flour = 4 eggs, 6 cups flour = 8 eggs.
1 tablespoon of olive oil, per three cups of flour.
Put the flour on a large board and make a well in the centre. Crack the eggs into the well and sprinkle with salt and oil . Use your fingertips to mix up the eggs and then start to incorporate the flour into the eggs. Eventually it will all come together. (add 1 to 2 tablespoons of water if necessary) Knead dough until smooth and elastical. Let sit covered for 15 or 20 minutes. Divide dough into smaller portions and run through a pasta rolling machine or roll out by hand. Let dry slightly and then cut into desire widths. Leave out to dry or use fresh. When dried she always stored it in a wax paper lined box, in a cool place.
You can also mix and knead this in the Cuisinart, which is what I do when I make it.
My friends mom would make 12 and 15 egg pasta at a time and give it to all of her family members (and me, a would-be family member). After she cut the pasta she would lay the strands flat. She would have it spread out everywhere there was a flat surface and also hang it from a broomstick strung between two drawers. Once it was dry she would gather up the stiff pieces and put them in boxes. Because I don't make that much at a time, I just lay it all over my table and counter.
NOTE: Depending on the flour and the eggs, sometimes you will need more eggs. Can also be made with egg yolks.
