Ingredients

• Shortbread Crumble
  1 cup (130 g) all-purpose flour
  1/4 cup (50 g) granulated sugar
  1/2 cup (115 g) unsalted butter, cold and cubed
  Pinch of salt
• Lemon Mousse
  3 large eggs, separated
  1/2 cup (100 g) granulated sugar
  1/3 cup (80 ml) freshly squeezed lemon juice (about 2 lemons)
  2 teaspoons finely grated lemon zest
  1/2 cup (120 ml) heavy cream, chilled
  1/4 teaspoon cream of tartar (optional, for stability)
• Garnish (optional)
  Fresh berries
  Lemon zest curls
  Mint leaves

Instructions

1. Preheat the oven to 350°F (175°C). Line a baking sheet with parchment paper.

2. Make the Shortbread Crumble:

In a bowl, combine flour, sugar, salt, and cold butter. Rub together with your fingertips or use a pastry cutter until mixture resembles coarse crumbs. Spread evenly on the prepared baking sheet.

3. Bake the crumble for 12–15 minutes, stirring halfway, until golden brown. Cool completely.

4. Prepare the Lemon Mousse:

In a medium heatproof bowl, whisk together egg yolks, 1/4 cup (50 g) sugar, lemon juice, and lemon zest. Place the bowl over a pot of simmering water (double boiler) and whisk constantly until thickened (about 7 minutes). Remove from heat and cool to room temperature.

5. In a clean bowl, beat egg whites (with cream of tartar, if using) until soft peaks form. Gradually add remaining 1/4 cup (50 g) sugar and beat until stiff peaks form.

6. In a separate bowl, whip the chilled cream to soft peaks.

7. Gently fold the whipped cream into the cooled lemon mixture. Then fold in the egg whites until just combined and smooth.

8. Assemble:

Spoon a generous layer of shortbread crumble into the bottom of 6 small serving glasses or ramekins. Top with lemon mousse. Chill for at least 2 hours before serving.

9. Garnish each cup with berries, lemon zest curls, and mint if desired.

Zusatztipps für die Zubereitung

Pay close attention to folding the whipped cream and egg whites gently into the lemon mixture to maintain the mousse's light, airy texture. Ensuring the shortbread crumble is fully cooled before layering prevents sogginess. Using fresh lemons for juice and zest intensifies the bright citrus flavor, essential to this dessert's character.

Varianten und Anpassungen

For a gluten-free version, substitute the all-purpose flour with a gluten-free blend. To add extra crunch and flavor, consider mixing toasted chopped almonds or pistachios into the crumble. These subtle tweaks personalize the dessert while respecting its classic profile.

Serviervorschläge

Serve chilled alongside a glass of Moscato or Prosecco for a delightful pairing that amplifies the mousse's citrus notes. Garnishing with fresh berries, lemon zest curls, and mint leaves not only enhances the presentation but also adds layers of fresh aroma and color.
