Ingredients

• 1 cup heavy whipping cream (240 ml)
• 1/2 cup granulated sugar (100 g)
• 3 large egg yolks
• 1/2 cup freshly squeezed lemon juice (120 ml)
• Zest of 1 lemon
• 1 teaspoon vanilla extract (5 ml)
• 1 tablespoon lemon liqueur or water (optional)
• Pinch of salt

How to make it

1. In a small bowl, whisk egg yolks and half the sugar until pale and smooth.

2. In a saucepan, combine lemon juice, lemon zest, remaining sugar, and salt. Heat over medium until sugar dissolves, about 2 minutes.

3. Slowly pour half the hot lemon mixture into the egg yolks, whisking constantly to prevent curdling.

4. Return the egg-lemon mix to the pan. Cook on low heat, stirring, until it thickens slightly (do not boil), about 2–3 minutes. Remove from heat.

5. Stir in vanilla extract and optional liqueur. Let the lemon curd cool to room temperature.

6. In a chilled bowl, whip heavy cream until soft peaks form.

7. Gently fold the cooled lemon curd into the whipped cream until streaks disappear.

8. Spoon the mousse into serving glasses or bowls. Cover and refrigerate for at least 2 hours.

9. Garnish with extra lemon zest or fresh berries before serving.

Tips and common mistakes

• Whisk eggs constantly when adding hot liquid to avoid scrambled eggs.
• Cool the lemon curd fully before folding to keep the mousse light.
• Use cold cream and bowl for best whipping volume.
• Don’t overwhip cream—stop at soft peaks to maintain fluffiness.

Substitutions

• Heavy cream: use half-and-half plus 2 Tbsp powdered sugar, but mousse will be less firm.
• Sugar: swap for honey (slightly less volume) for a different sweetness note.
• Lemon juice: use lime juice for a lime mousse twist.

Storage instructions

Store covered in the fridge for up to 2 days. The mousse may soften over time but stays tasty. Best served within 24 hours for fluffy texture.
