"You date round ravioli. You marry square ravioli."

That's humorist and Cooking Channel host Mo Rocca talking about his favorite ravioli shapes.

"Like a lot of things, I'm torn between what I actually want and what I think I should want," Mo adds. "And there's a whole lot of guilt mixed in."

Mo Rocca is all about details, and his stories on CBS Sunday Morning often nerd out on language, history, and science.

His Cooking Channel show, My Grandmother's Ravioli, features grandparents from around the country teaching Mo how to cook everything from spanikopita to shrimp ceviche.

The show's name pays homage to Mo's own grandmother and her ravioli.

"The whole series was driven by guilt for not having helped my grandmother in the kitchen, so I feel particularly protective of her ravioli," Mo admits.

In the spirit of Grandma Rocca's ravioli, Mo and Dan don't shy away from the big issues: ravioli grammar, trim-to-pouch ratios, and the anxiety of the disemboweled raviolo. (Yep, that's the proper term for a single square or circle.)

Listen in to the full episode to hear why Mo describes his relationship with ravioli as a "Madonna-whore sort of thing" and to learn which type he calls the "Kenny G of ravioli."
