How to Make Lemon Tiramisu: Step-by-Step
Step 1: Make the Lemon Syrup
Start by preparing the lemon syrup. In a medium saucepan, combine freshly squeezed lemon juice, water, sugar, and lemon zest. Cook over medium heat, stirring occasionally until the sugar dissolves and the mixture comes to a simmer. Let it cook for about 5 minutes, then remove it from the heat and allow it to cool in the refrigerator.
Step 2: Prepare the Lemon Curd
For the lemon curd, whisk egg yolks, a whole egg, granulated sugar, lemon juice, zest, and salt in a saucepan. Add butter and cook over medium-low heat, stirring constantly until it thickens. Strain the curd to remove any lumps, cover it with plastic wrap, and refrigerate until cool.
Step 3: Make the Mascarpone Filling
In a stand mixer, whip heavy cream to stiff peaks. In a separate bowl, combine mascarpone cheese, sugar, lemon syrup, and vanilla. Beat until smooth, then gently fold in the whipped cream for a light and airy filling.
Step 4: Assemble the Tiramisu
To assemble, dip ladyfingers one at a time into the cooled lemon syrup, ensuring they soak without becoming soggy. Arrange them in an even layer at the bottom of an 8-inch square dish. Spread half of the lemon curd over the ladyfingers, followed by half of the mascarpone filling. Repeat the layers with the remaining ingredients.
Step 5: Final Touches
For the top layer, pipe the remaining mascarpone filling over the tiramisu to create a decorative effect. Refrigerate for at least 6 hours before serving to allow the flavors to meld together and for the dessert to set properly.
