Food-obsessed broadcaster Dan Pashman has invented a new pasta shape that has gone into commercial production.

Pashman, host of the Cooking Channel's "You're Eating it Wrong," author of the book "Eat More Better," and host of podcast "The Sporkful," designed cascatelli--that's Italian for "waterfall"--to get top marks in his trinity of required pasta qualities:

1. Sauceability: How readily sauce adheres to the shape

2. Forkability: How easy it is to get the shape on your fork and keep it there

3. Toothsinkability: How satisfying it is to sink your teeth into it

Pashman worked with New-York-based Sfoglini Pasta to get the new shape into production, and it's been a huge hit: 16-ounce boxes and four-packs are completely sold out, with only 5-lb bulk bags available--and there's an 8-week shipping period.

The story of how Pashman came to invent the shape has been captured on "The Sporkful."
