Just wanted to report that we made Marcella Hazan's recipe last night. Our conclusion was that the simple 4 ingredient recipe was better. We will add some parsley as a garnish. The olive oil, wine, and garlic really did not add anything and it was not as creamy as the one I made earlier in the week. If I can get my hands on some Guinciale I will try using it. That might be an excuse to go to Cincinnati and shop Jungle Jim's.
