You know those two things hanging off the ends of your arms that you use to text people? They're also fantastic at molding raw meat into a circular shape, and they're way more useful than anything you'll find in the "As Seen on TV" section of Walgreens.

You'll make fantastic pasta one time, and then go back to making pasta in two minutes in boiling water from that point on.
