Why This Recipe Works

• It has a refreshing mojito flavor, with fresh lime and white rum, giving the classic tiramisu a bright, citrusy twist. The egg-based filling is rich and silky. Using eggs instead of whipped cream creates a more traditional tiramisu texture while keeping the filling light and creamy.
• The lime curd adds the perfect contrast. Its sweet-tart flavor cuts through the mascarpone's richness, making every bite more balanced.
• It is a beautiful make-ahead dessert. The tiramisu needs several hours in the refrigerator to soften the ladyfingers and set the filling.
• The whipped cream decoration keeps the finish elegant. A piped border around the edge adds height and softness without making the filling itself heavy.
• It is perfect for special occasions. The combination of pale lime curd, creamy mascarpone, and fresh lime makes this an impressive centerpiece.
  

Lime Mojito Tiramisu Ingredients

See the recipe card for full information on ingredients and quantities.

• Limes: Fresh limes are essential for the best flavor. You will need lime juice and zest for the filling and soak, as well as fresh lime for decorating.
• White rum: Use a good-quality white rum for the mojito-inspired flavor. You can reduce or omit the rum if preferred.
• Mascarpone: Use full-fat mascarpone for the richest, smoothest filling. It should be cold before mixing.
• Eggs: Use fresh eggs and carefully separate the yolks from the whites.
• Ladyfingers: Use crisp Italian-style ladyfingers. They absorb the lime-and-rum mixture beautifully without becoming overly soggy when dipped properly.
• Heavy cream/double cream: Used only for the decorative whipped cream border, not incorporated into the mascarpone filling. Ensure that the cream is cold before whipping.
• Mint: Fresh mint can be used as an optional garnish for an extra mojito-inspired finish.

Tips and Substitutions

• Lime curd: Cool the lime curd completely. The curd should be completely cool before spreading it over the tiramisu. Warm curd can soften the mascarpone layer.
• Mixing: Don't overmix the mascarpone. Mix just until smooth and combined. Overmixing can cause mascarpone to become loose or split.
• Eggs: Whip the egg whites carefully. Fold them gently into the mascarpone mixture to preserve as much air as possible.
• Egg-free: You can use an egg‑free filling if you prefer, just check the top tip notes for a simple breakdown on how to make it.
• Ladyfingers: For this recipe, dip the ladyfingers into the lime soak very quickly to prevent them from becoming too soggy.

How to Make Lime Mojito Tiramisu

Prepare the Lime Curd: First, follow the recipe instructions to make the homemade lime curd. Allow the finished curd to cool completely. Once cool, cover the surface of the curd with plastic wrap and refrigerate until needed.

Step 1: Separate the eggs, placing the egg whites in a bowl.

Step 2: Add the egg yolks to a separate large mixing bowl.

Step 3: Add the sugar to the egg yolks.

Step 4: Whisk for 3-5 minutes or until the mixture becomes pale, creamy and thickened.

Step 5: Add the mascarpone to the egg yolk mixture.

Step 6: Whisk gently until the mascarpone is completely incorporated and the mixture is smooth. Avoid overmixing.

Step 7: In a separate clean bowl, whisk the egg whites until they form stiff peaks.

Step 8: Add one-third of the whipped egg whites to the mascarpone mixture.

Step 9: Gently fold the egg whites through the mascarpone mixture using a spatula. Repeat with the remaining egg whites, folding gently until the filling is light, smooth and evenly combined.

Step 10: Add freshly squeezed lime juice, water and white rum to a shallow bowl. Stir well to combine. Taste the mixture and adjust the balance of lime and rum if necessary.

Step 11: Dip each ladyfinger into the lime and white rum mixture for 1-2 seconds.,

Step 12: Arrange the soaked ladyfingers in a single layer across the bottom of your serving dish.

Step 13: Spread half the mascarpone filling evenly over the ladyfingers.

Step 14: Add another layer of lime and rum-soaked ladyfingers.

Step 15: Spread the remaining mascarpone filling over the second layer of ladyfingers. Smooth the surface evenly. Cover the tiramisu and refrigerate for at least six hours, preferably overnight. This lets the ladyfingers soften and the mascarpone filling set properly.

Step 16: Remove the chilled tiramisu from the refrigerator and gently spread the cooled lime curd over the entire surface. Smooth the lime curd carefully with a spatula to create an even, glossy layer.

Step 17: Whip the double cream until it reaches stiff peaks. Transfer it to a piping bag fitted with your preferred nozzle. Pipe the whipped cream around the outer edge of the tiramisu to create a neat decorative border.

Step 18: Add lime zest around the border.

Step 19: Place a fresh lime slice and mint in the center of the tiramisu.

Step 20: If the curd is too liquid, refrigerate it for 20-30 minutes before serving to help it set.

Step 21: Serve and enjoy this refreshing Lime Mojito Tiramisu at summer gatherings, dinner parties, birthdays and other special occasions.
