Description

This refreshing Lemon Mousse recipe is a light and airy dessert highlighting the bright flavors of fresh lemons. Made with lemon juice, zest, eggs, gelatin, and whipped cream, it delivers a perfectly balanced tartness and creamy texture. Easy to prepare and chilled to set, it’s an elegant treat ideal for warm weather or whenever you crave a citrusy indulgence.


Ingredients

Scale

For the Lemon Mousse

  • 3 large lemons (juiced and zested)
  • ½ cup granulated sugar
  • 2 large eggs
  • 1 cup heavy cream
  • 1 tablespoon gelatin powder
  • 3 tablespoons cold water
  • 1 teaspoon vanilla extract
  • Pinch of salt


Instructions

  1. Prepare the Gelatin: In a small bowl, combine the gelatin powder with cold water and let it bloom for about 5 minutes.
  2. Whisk Eggs and Sugar: In a medium saucepan, whisk together the eggs and granulated sugar until the mixture is pale and fluffy.
  3. Add Lemon Juice and Zest: Stir in the lemon juice, lemon zest, and a pinch of salt. Cook the mixture over low heat, stirring constantly, until it thickens enough to coat the back of a spoon (about 5-7 minutes).
  4. Dissolve Gelatin: Remove the lemon mixture from heat and add the bloomed gelatin, stirring thoroughly until it fully dissolves. Allow the mixture to cool slightly.
  5. Whip Cream: In a separate bowl, whip the heavy cream until soft peaks form, being careful not to overwhip.
  6. Combine Mixtures: Gently fold the cooled lemon mixture into the whipped cream using a spatula, combining well while maintaining the airy texture.
  7. Chill: Spoon the mousse into serving cups or a large bowl, cover, and refrigerate for at least 2 hours until set.
  8. Serve: Once chilled and set, garnish as desired and serve chilled for a refreshing dessert.

Notes

  • Ensure the lemon mixture cools slightly before folding in whipped cream to prevent deflating.
  • You can garnish with lemon zest, fresh berries, or a mint sprig for a pretty presentation.
  • Do not overwhip the cream to maintain lightness in the mousse.
  • Refrigeration for 2 hours or more helps the mousse set properly thanks to the gelatin.
  • Use fresh lemons for the best citrus flavor.
