Step-by-Step Instructions

Step 1: Prepare the Lemon Curd

1. In a heatproof bowl, whisk together the egg yolks and granulated sugar until smooth.
2. Add the lemon juice and lemon zest, mixing well.
3. Place the bowl over a saucepan of gently simmering water (double boiler).
4. Cook while stirring constantly until the mixture thickens and coats the back of a spoon.
5. Remove from heat and stir in the butter until fully melted and smooth.
6. Cover the surface with plastic wrap and refrigerate until completely cooled.

Step 2: Make the Lemon Syrup

1. In a small saucepan, combine water, sugar, lemon juice, and lemon zest.
2. Bring to a gentle boil, then reduce heat and simmer for 5–7 minutes.
3. Remove from heat and let the syrup cool completely.
4. Strain out the zest if desired.

Step 3: Prepare the Mascarpone Cream

1. In a large bowl, whip the heavy cream until stiff peaks form.
2. In a separate bowl, whisk the mascarpone cheese with powdered sugar and vanilla extract until smooth.
3. Gently fold the whipped cream into the mascarpone mixture.
4. Add 2–3 tablespoons of lemon syrup and fold gently until combined.

Step 4: Assemble the Lemon Tiramisu

1. Quickly dip each ladyfinger into the cooled lemon syrup (do not soak).
2. Arrange a layer of soaked ladyfingers in the bottom of a serving dish.
3. Spread a layer of lemon curd evenly over the ladyfingers.
4. Add a layer of mascarpone cream and smooth the top.
5. Repeat the layers: ladyfingers, lemon curd, and mascarpone cream.
6. Finish with a final layer of mascarpone cream on top.

Step 5: Chill and Serve
