TIRAMISÚ ''IN LEGGEREZZA'' - light tiramisú

I love tiramisú and I could eat it almost every day. But, as you know, with its indulgent cream with mascarpone, eggs and sugar it is a very rich dessert (and a nasty friend if you are trying to lose weight).
I wanted thus to prepare a lighter version, to eat without regrets. Replacing mascarpone with the freshness of ricotta and yogurt, I had a very balanced light cream, both in taste and in consistency, that made my tiramisú as good as the original one.
