Pasta with walnuts and Ricotta

Tonight I watched three cooking shows--Italian, Mexican (I think), and Thai. But they were all using Italian cheeses. Anyway, I just love walnuts and eat them everyday. I decided to look up Lydia's show (it was a 2009 rerun) and found a blog which described what I saw, and explained about roasting the walnuts, since Lydia's were purchased that way. I don't think the pasta I saw on the show was Fettucini, but I'm not sure she said. Check out Plated, Jessica and James, a musician and painter who live in NY and love to cook.
