Description

This luscious Lemon Mousse is the ultimate no-bake dessert that combines tangy citrus flavors with a creamy, airy texture. Perfectly balanced with fresh lemon juice, zest, and whipped cream, this French-inspired treat is light yet indulgent, ideal for any occasion.


Ingredients

Scale

Gelatin Mixture

  • 1 teaspoon unflavored gelatin
  • 2 tablespoons cold water

Lemon Mixture

  • 3 large egg yolks
  • 1/2 cup granulated sugar
  • 1/2 cup freshly squeezed lemon juice
  • 1 tablespoon lemon zest

Whipped Cream

  • 1 cup heavy whipping cream
  • 1 teaspoon pure vanilla extract

Egg Whites

  • 3 large egg whites
  • 1/8 teaspoon salt


Instructions

  1. Bloom Gelatin: In a small bowl, sprinkle the unflavored gelatin over 2 tablespoons of cold water and let it bloom for 5 minutes until fully absorbed and gelatin softens.
  2. Prepare Lemon Base: In a heatproof bowl, whisk the egg yolks with 1/2 cup granulated sugar until the mixture becomes pale and slightly thickens. Stir in the freshly squeezed lemon juice and lemon zest to infuse vibrant citrus flavor.
  3. Cook Lemon Mixture: Place the bowl over a saucepan of simmering water (double boiler setup). Cook the lemon mixture while stirring constantly for about 5 to 7 minutes until it thickens slightly and coats the back of a spoon.
  4. Add Gelatin: Remove the bowl from heat and immediately stir in the bloomed gelatin until it dissolves completely. Set the lemon mixture aside and let it cool to room temperature to prevent deflating the mousse later.
  5. Whip Cream: In a separate chilled bowl, whip the heavy cream together with vanilla extract until soft peaks form, ensuring a light, creamy texture for the mousse.
  6. Beat Egg Whites: Using a clean bowl, beat the egg whites with salt until stiff peaks form. This adds volume and airy softness to the mousse.
  7. Combine Mixtures: Gently fold the whipped cream into the cooled lemon mixture, preserving the airiness. Then carefully fold in the beaten egg whites until the mixture is fully incorporated and smooth, avoiding any deflation.
  8. Chill Mousse: Spoon the finished lemon mousse into serving glasses or bowls. Refrigerate for at least 3 hours or until completely set to achieve the perfect light and creamy consistency.

Notes

  • For a stronger lemon flavor, increase the lemon zest by one extra teaspoon.
  • Ensure the lemon mixture is fully cooled before folding in the whipped cream to maintain the mousse’s light texture.
  • This dessert can be prepared one day ahead and kept covered in the refrigerator for convenience.
