Only the mascarpone and the ladyfingers in this lemony dessert give a nod to a traditional tiramisu, but my California spin on this beloved dessert is just as addictive. I think lemon makes everything taste a bit lighter (so I can eat more without feeling weighed down!), and the hazelnuts add a delicate flavor and lots of crunch. So while no one will mistake this for the original, I promise it will make anyone you serve it to very, very happy.
