Tagliatelle with Prosciutto

Like Proust with his madeleine, if I close my eyes when I eat this dish I am transported to another time and place. I feel as if I were back in Cesenatico, the town on the Adriatic where my mother was born and where I spent most of my summers growing up. This is the quintessential pasta dish of the Romagna part of Emilia-Romagna: homemade egg noodles with lots of butter, prosciutto, and Parmigiano-Reggiano cheese. How can you go wrong?
