When making homemade pasta you have several options in forming your noodles. You can extrude it (like my play dough experiment
), run it through a dedicated pasta machine, cut individual noodles, or as this instructable demonstrates, you can roll the dough and cut noodles very efficiently and quickly.
Once you get your dough as thin as you desire, simply roll it into a tube, and using a sharp knife, slice it as thin as you want.
Once you get the dough cut into spirals, simply unroll each spiral into a long noodle, and either dry or cook immediately.
This is a very simple way of cutting pasta noodles, and I hope it makes your life easier.
