Seafood is a common part of the traditional Italian diet. Mussels and clams appear in many Italian pasta dishes. This creamy pasta with mussels and clams is incredibly simple to make and is so quick that you can cook it for your family after work. After sweating the shallots, a sauce is made from white wine, butter, heavy cream and clam juice to increase the seafood flavors. I used frozen mussels and clams in this recipe because my grocer did not have fresh shellfish here in Ohio when the mood to cook this dish hit me.
