Did you sub at 1:1, I am starting out and not always sure on the subbing and % changes. This looks good and I would love to make it, but also do not have PUR in my collectionIt's not particularly sweet, there is sweetness in it of course but the tartness of the granadilla balances it well.
I did use CAP New York Cheesecake though - I don't have the PUR version.
