Rolling and Cutting Pasta by Hand: It can be done! Divide the dough into four pieces and mimic the action of a pasta roller with a rolling pin. Roll as thin as possible, lifting and moving the dough constantly to make sure it doesn't stick. Sprinkle the dough generously with flour and then gently roll it up. Use a very sharp chef knife to cut the roll cross-wise into equal-sized noodles. Shake out the coils, toss with flour, and proceed with cooking.
