Return of Mo Rocca and the Grandmothers

Mo Rocca, host of "My Grandmother's Ravioli."

Mo Rocca, panelist on "Wait Wait Don't Tell Me" (and lots more), discusses the new season of his show "My Grandmother's Ravioli" on the Cooking Channel and takes listener calls.

Also, Ruth Taube talks about teaching Mo Rocca how to make matzo ball soup and farfel, where to find the best pickles and black and white cookies, and her own history with the Henry Street Settlement, where she created the Home Planning Workshop in 1966.
