Whisk together the eggs and sugar in a saucepan over low heat.
Add the lemon juice, zest, and salt to the pan and heat over medium-low. Cook until the sugar is dissolved, whisking constantly.
Turn the heat to low and stir in the butter.
Whisk the mixture for 5-6 minutes or until it has thickened enough to coat the back of a spoon.
Remove the pan from the heat and whisk in the vanilla.
Run the curd through a fine mesh strainer into a bowl. Allow the curd to cool before storing it in the fridge.
Prepare lemon syrup.
Combine the sugar, lemon juice, lemon zest, and water in a small saucepan and cook over medium heat until the sugar completely dissolves about 3-4 minutes.
Remove from the heat and cool completely.
Prepare cream.
Beat the mascarpone, cream cheese, lemon zest, powdered sugar, and vanilla until creamy in a bowl.
In a separate bowl, beat heavy cream until soft peaks form. Add to the mascarpone cream mixture and beat over low heat until combined.
Assemble.
Add a thin layer of cream to the bottom of a 9x13-inch baking dish.
Dip half of the 25 ladyfinger cookies quickly in the cooled syrup until fully coated and arrange them in a baking dish.
Layer half of the cream mixture over the cookies and half of the curd.
Repeat this with the remaining cookies, cream, and curd. You will need two layers.
Refrigerate at least 2 hours or overnight, tightly covered.
Garnish as desired.
Notes
Prepare in advance. Make the lemon curd and syrup in advance for an easier assembly process. Both can be stored in the fridge for 5 days before using.
Use fresh ingredients. Fresh lemon juice is the key to the best flavor in a lemon cake.
Storage. Leftover tiramisu can be stored in an airtight container in the fridge for 3-5 days.
Dip the ladyfingers quickly in the syrup to prevent them from getting soggy.
