Using a hand-cranked machine

Divide the dough into balls the size of oranges. Work on one ball at a time, leaving the others to rest, wrapped in clingfilm. Adjust the smooth kneading rollers of the machine to their widest setting, and pass the ball through six or seven times, folding it over and turning it 90 degrees after each rolling. Whenever the dough sticks to the rollers, sprinkle the rollers with flour. After six or seven times, do not fold the sheet any more. Adjust the rollers to the next thinnest setting, and pass the dough through once. Repeat for each remaining roller setting, passing the unfolded sheet once through each of them. If the strip of dough gets too long (more than 50cm/20 inches or so), cut it in half and proceed with one half at a time.
