1. Make the Lemon Syrup:

• Combine lemon juice and sugar in a shallow dish. Whisk until the sugar dissolves completely.

2. Prepare the Mascarpone Filling:

• In a large bowl, beat mascarpone cheese until smooth and creamy.
• Gradually add lemon curd, beating until well combined and fluffy.
• In a separate bowl, whip heavy cream until stiff peaks form.
• Gently fold the whipped cream into the mascarpone mixture until evenly incorporated.

3. Assemble the Tiramisu:

• Dip a ladyfinger into the lemon syrup for a few seconds, turning to coat both sides. Don’t oversaturate, as the cookies will become soggy.
• Place dipped ladyfingers in a single layer at the bottom of your serving dish.
• Spread half of the mascarpone filling evenly over the soaked ladyfingers.
• Repeat the dipping and layering process with another layer of ladyfingers and the remaining mascarpone filling.

4. Chill and Set:

• Cover the dish tightly with plastic wrap.
• Refrigerate for at least 4 hours, or ideally overnight. This allows the flavors to meld and the ladyfingers to soften.
