How to make Lemon Tiramisu

Ingredients:
4 large egg yolks, 2/3 cup granulated sugar ((134g) ), 1 Tablespoon lemon zest ((6g), about 1 lemon), 1/3 cup lemon juice ((80mL), fresh squeezed (or you could use limoncello)), pinch salt, 6 Tablespoons unsalted butter ((85g), room temperature, chopped), ¾ cup lemon juice ((180mL), fresh squeezed, from about 2-3 lemons), 1 cup water ((240mL)), 1/2 cup granulated sugar ((100g)), 1/4 cup limoncello ((60mL), (optional*)), 8 oz mascarpone cheese ((226g), room temperature), 1 Tablespoon lemon zest ((6g)), 1 ½ cups heavy whipping cream ((360mL)), 1 package Lady Fingers (, (7 oz package, about 24 lady fingers, Savoiardi brand)*), white chocolate (, grated on top, as garnish (optional))

Directions:
Zest and juice lemons and set aside.
Lemon Curd: Add 2 inches of water to the bottom of a small saucepan and bring to a simmer over medium heat. In a heat-proof mixing bowl, add 4 egg yolks, 2/3 cup granulated sugar, 1 Tablespoon lemon zest, 1/3 cup lemon juice, and a pinch of salt and whisk well to combine. Place bowl over pot of water, reduce heat to medium low and cook, whisking constantly, until mixture thickens to a gravy consistency, about 7-10 minutes. Remove bowl from heat and stir in 6 tablespoons butter.
Cool Lemon Curd: Pour mixture into a new bowl and place a piece of plastic wrap directly on the surface (to prevent it from forming a skin). Refrigerate whie you prepare the rest of the ingredients.
Lemon Syrup: In a saucepan, add ¾ cup lemon juice, 1 cup water, and ½ cup sugar. Bring to a boil, stirring to dissolve the sugar. Boil for 5 minutes, then remove from heat. Transfer to a bowl and cool completely to room temperature (or refrigerate to cool down faster). Stir in ¼ cup limoncello (if using).
Whipped Mascarpone: Combine mascarpone with 1 Tablespoon lemon zest then mix in the whipping cream with an electric mixer just until medium/stiff peaks (don’t over-mix).
Assemble: Submerge each lady finger quickly in lemon syrup and then place in the bottom of an 8×8 or similar size pan, until bottom of pan is lined. Top with half of the whipped mascarpone. Stir lemon curd well then spoon over the top, into an even layer. Repeat with another layer of dipped lady fingers. Smooth (or decoratively pipe) remaining whipped mascarpone on top. Optional: garnish with grated white chocolate and/or lemon zest or lemon slices.
Refrigerate for at least 2 hours, or overnight.

How to serve Lemon Tiramisu
Serve slices chilled straight from the fridge so the layers stay distinct and the lemon curd has set into silky ribbons. Garnish with a fine grating of white chocolate and a few curls of lemon zest for brightness. Serve with a small cup of espresso or a light sparkling wine to balance the citrus.

How to store Lemon Tiramisu
Cover the pan tightly with plastic wrap or transfer to an airtight container and refrigerate for up to 3 days. The texture is best within the first 48 hours. Do not freeze — freezing will alter the delicate texture of the mascarpone and curd.

Tips to make Lemon Tiramisu

  • Use room-temperature mascarpone and butter so they blend smoothly without lumps.
  • Don’t soak ladyfingers too long — a quick dunk keeps them tender without turning mushy.
  • Chill the lemon curd beneath plastic wrap to prevent a skin from forming.
  • Whip cream to medium-stiff peaks: overwhipping will break the airy texture.
  • If you’d like more zing, fold in an extra teaspoon of fresh lemon zest into the mascarpone layer.

Variations (if any)

  • Limoncello-Boosted: Increase limoncello to 1/3 cup and reduce syrup water slightly for a boozy, grown-up version.
  • Berry Twist: Layer macerated raspberries between the mascarpone and curd for a bright contrast.
  • Earl Grey Lemon: Infuse the lemon syrup with an Earl Grey tea bag while boiling for an aromatic, bergamot-forward note.

FAQs
Q: Can I make the components ahead of time?
A: Yes — the lemon curd can be made up to 3 days ahead and stored in the fridge. Whipped mascarpone is best assembled the day you plan to serve, but you can prepare it the night before and keep it chilled.

Q: Is it safe to use raw egg yolks in the curd?
A: The curd is cooked over simmering water until thickened, which brings the eggs to a safe temperature. If you’re concerned, use pasteurized eggs or cook the curd carefully until it reaches a thick custard consistency.

Q: Can I substitute something for mascarpone?
A: Mascarpone provides a unique, silky richness; a mix of cream cheese and heavy cream (3:1 ratio) can work in a pinch, but taste and texture will differ slightly.

Q: How do I make this non-alcoholic?
A: Simply omit the limoncello and replace with an equal amount of water or extra lemon juice in the syrup; you’ll still get bright flavor from the fresh lemons.

Q: My mascarpone mixture is too runny — how can I fix it?
A: Chill it for 20–30 minutes to firm up, then gently rewhip to medium peaks. If still runny, fold in a tablespoon of sifted powdered sugar or a little more chilled whipped cream.
