I need some help.
I'd love to make cheesecake in my bakery, but in France we don't have anything that comes close to cream cheese.
Any suggestions?

Mascarpone, I use Cream Cheese to substitute for Mascarpone when making Tira Misu why not substitute cream cheese with Mascarpone when making Cheese Cake.
Can't find Mascarpone her is a link that mentions how to make it.

Really any cheese that is unaged, relatively fresh curd will do, here in the U.S. that includes, Cottage Cheese, Farmers Cheese, Riccota.

"Farmers Cheese, Riccota"
if your going to use these kinds remember to add a whole lot more eggs.
but they do make a great tasting cake.
good luck.

Thanks for the help.
