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

Ensure the butter is very cold when making the shortbread crumble for a crisp texture. Whisk the lemon mousse mixture constantly over the double boiler to prevent curdling and achieve a silky finish. When folding the whipped cream and egg whites, do so gently to maintain the mousse's light and airy consistency.

Varianten und Anpassungen

For a gluten-free option, substitute the all-purpose flour with a gluten-free flour blend. To add extra crunch and flavor, mix in toasted chopped almonds or pistachios into the crumble. The lemon intensity can be adjusted by varying the amount of lemon juice and zest as preferred.

Serviervorschläge

Serve chilled lemon mousse cups garnished with fresh berries, lemon zest curls, and mint leaves for a vibrant presentation. Pair this dessert with a cold glass of Moscato or Prosecco to complement its bright citrus flavors, perfect for spring or summer occasions.
