Ingredients

Scale

Ingredients

  • 2 large fresh lemons (zest and juice)
  • 1/2 cup granulated sugar
  • 1 cup heavy whipping cream, chilled
  • 3 egg whites, room temperature

Instructions

  1. Prepare Lemon Juice and Zest: Zest the lemons carefully to collect about a teaspoon of zest, then juice the lemons until you have approximately one cup of fresh lemon juice. Set aside.
  2. Whip the Heavy Cream: Using a mixer, whip the chilled heavy cream in a mixing bowl until soft peaks form. This means the cream should hold shape but still be smooth and slightly floppy.
  3. Warm Egg Whites and Sugar: In a heatproof bowl set over simmering water (double boiler), whisk together the sugar and egg whites constantly until the mixture is warm to the touch and the sugar has dissolved completely, about 3-4 minutes.
  4. Beat Egg Whites to Stiff Peaks: Remove the egg white mixture from the heat. Using an electric mixer, beat the mixture until it forms stiff, glossy peaks that hold firm when the beaters are lifted.
  5. Fold Ingredients Together: Gently fold the whipped cream into the stiff egg whites to combine without deflating the mixture. Then fold in the lemon juice and zest carefully until evenly incorporated.
  6. Chill the Mousse: Spoon or pour the mousse into serving glasses or bowls. Cover each with plastic wrap and refrigerate for at least four hours, allowing the mousse to set and develop flavor.
  7. Serve: Serve the mousse chilled. Optionally garnish with additional lemon zest or fresh berries to enhance presentation and taste.

Notes

  • Use room temperature egg whites for better volume when whipping.
  • Ensure heavy cream is well chilled before whipping for optimal texture.
  • For a firmer mousse, you can chill longer or refrigerate overnight.
  • If you prefer sweeter mousse, adjust sugar quantity slightly but be careful not to overshadow the lemon flavor.
  • This mousse contains raw egg whites; use pasteurized eggs if concerned about food safety.
  • Garnishes such as mint leaves or raspberries pair wonderfully with lemon mousse.
