Instructions: 

1. Cook pasta in a large pot of boiling salted water, stirring occasionally, until al dente, about 10 mins. Drain over a bowl to reserve the cooking liquid and let sit.
2. Meanwhile, in a medium sized sauté pan, cook the prosciutto over medium heat until crisp, about 5 mins.
3. In a large mixing bowl, add ricotta, lemon zest, orange zest, Parmesan cheese, basil, parsley, and season with salt & pepper to taste. Using a ladle, add a ¼ cup of the reserved pasta cooking liquid to the ricotta mixture and stir to combine until the desired consistency is reached.
4. Toss the cooked pasta with the ricotta mixture until fully coated. Garish with crispy prosciutto, walnuts, and freshly grated Parmesan cheese. Serve and enjoy!
