Thank you very much! I especially appreciate the cream cheese note and the aluminum foil note.

... I don't really know how mascarpone differs from cream cheese: my instinct would be to use the latter because that's what I've used in the past (I don't think I've ever actually used mascarpone, though I've seen it sitting next to the cream cheese in the supermarket), but do they taste very different? If I'm going to be doing myself out of the true experience by using cream cheese, I'll use the mascarpone.
