In a small saucepan on the stove, heat lemon juice, sugar, limoncello and water over medium heat. Whisk until the sugar has dissolved. Set aside to cool.
Using a stand mixer fitted with the whisk attachment or a large mixing bowl and electric hand mixer, whisk the heavy cream until firm peaks form. *Note: For the best results, chill the mixing bowl and whisk attachment in the freezer or refrigerator before whipping the cream.
Transfer the whipped cream from the mixing bowl to a separate bowl. Set aside.
In the same mixing bowl (you don’t have to wash it!), add the mascarpone, lemon curd and lemon zest. Combine at medium-high speed until mixture is smooth.
Using a spatula, gently fold the whipped cream into the mascarpone mixture until combined.
Layer half of the ladyfinger cookies in the bottom of an 8-inch square dish. *Note: You might have to cut off the ends of the cookies with a sharp knife so they'll fit.
Drizzle half of the lemon syrup over the ladyfingers, making sure to saturate them evenly.
Spread half of the mascarpone/whipped cream mixture over the top of the soaked lady fingers. Use an offset spatula or the back of a spoon to spread ½ cup lemon curd evenly over the whipped cream.
Layer with the remaining ladyfingers, drizzle them with the remaining lemon syrup, then cover with the remaining mascarpone mixture and ½ cup lemon curd.
Cover the dish with plastic wrap and refrigerate for at least 8 hours, or overnight if possible.

Do not over soften the mascarpone cheese. The fat can easily separate, causing the cheese to curdle. It’s fine to take it out of the fridge 5 minutes before you’re ready to use it.
Make this dessert 24 hours before you plan to serve it. Tiramisu is best made in advance of serving it so the cookies can soak up the liquid and the flavors can meld together!
Ladyfingers are the authentic choice for a tiramisu recipe. If you need a substitute, the best choice is to cut pieces of sponge cake or vanilla pound cake in an oblong shape similar to ladyfingers, but the dessert really won't be the same.
There are really no good substitutes for mascarpone cheese. It's a very rich cheese that is much higher in fat than cream cheese.
