You are making peach gelato and it calls for mascarpone what can you substitute for mascarpone?

A basic substitution would be to use cream cheese instead. If you have a little time, a mixture of 1 tablespoon of cream mixed with every 8 ounces of softened cream cheese is better. If you don't have cream handy, you can use butter to blend with the cream cheese instead. Or use 1/4 cup of whipped cream.
