I always find this in my specialty cheese aisle at the grocery store, however, if it is not available for you you can substitute for additional cream cheese and prosciutto. I prefer the log because it makes for an easy, realistic, sturdy wrist bone for creating the structure of the hand, but you can simply sculpt a wrist out of an extra 8 oz of cream cheese and cover with an extra 2 oz of prosciutto! (Don't forget to increase your seasonings a little bit to compensate for this extra dip!)
