Description

A bright and creamy lemon mousse made with fresh lemon juice, whipped cream, eggs, and optional lemon curd for extra citrus flavor.


Ingredients

Scale
  • 6 large eggs, divided as 3 whole eggs, 3 egg yolks, and 3 egg whites
  • 1 cup plus 2 tablespoons granulated sugar, divided
  • Zest of 1 lemon
  • 1/2 cup fresh lemon juice, from about 3 to 4 lemons
  • 1/8 teaspoon salt
  • 1/2 cup heavy whipping cream
  • 1/2 cup lemon curd, optional
  • Whipped cream, optional, for topping
  • Extra lemon zest, optional, for garnish

Instructions

  1. Separate three eggs, keeping the whites in one bowl and the yolks in another. Add the three yolks to a large heatproof bowl with three whole eggs.
  2. Whisk in 1 cup granulated sugar, lemon zest, lemon juice, and salt until smooth.
  3. Fill a saucepan with a few inches of water and bring it to a boil. Reduce the heat to a simmer.
  4. Place the heatproof bowl over the simmering water, making sure the bowl does not touch the water.
  5. Cook while stirring constantly for about 15 minutes, until the lemon mixture thickens and reaches about 150°F.
  6. Remove the bowl from the heat and cool the mixture for 15 minutes.
  7. Press plastic wrap directly onto the surface of the lemon mixture and refrigerate for at least 2 hours, until fully chilled.
  8. Beat the reserved egg whites on high speed for 1 minute. Add the remaining 2 tablespoons sugar and continue beating until stiff peaks form.
  9. Gently fold the whipped egg whites into the cold lemon mixture without deflating them.
  10. Whip the heavy cream on high speed until stiff peaks form.
  11. Gently fold the whipped cream into the lemon mixture until combined.
  12. Fold in lemon curd if using.
  13. Spoon the mousse into serving cups or one serving bowl and chill for at least 30 minutes before serving.
  14. Top with whipped cream, lemon curd, or lemon zest if desired and serve cold.

Notes

  1. Use fresh lemon juice for the brightest flavor.
  2. Chill the lemon base completely before folding in the egg whites and whipped cream.
  3. Fold gently with a spatula to keep the mousse light and airy.
  4. Store covered in the refrigerator for up to 5 days.
  5. Do not freeze, because the texture may separate after thawing.
