I enjoyed this as made as directed, but I intend to experiment by using blue cheese instead of the ricotta, and/or mascarpone. versatile recipe, I also didn't have walnuts so I used almonds, but walnuts might be the better choice. Feel free to experiment! Oh, I used a 400 gr packet of tortellini, that's what I had. Use the variety that suits you, I think a butternut-filled tortellini might be lovely with this. There's no garlic used, and I didn't add any this time, but hey, I like garlic! Next time, maybe! Finish off with a good grinding of black pepper. From "Kitchen Classics : The Italian Kitchen"
