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

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

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. Beat egg whites

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. Whip the cream

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

7. Fold ingredients

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

8. Assemble the dessert

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

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

Zusatztipps für die Zubereitung

Ensure the butter for the crumble is cold to achieve a crumbly texture. When folding the egg whites and cream into the lemon mixture, gently combine to maintain the mousse’s light and airy texture. Chilling the dessert sufficiently helps the mousse set properly and enhances the refreshing lemon flavor.

Varianten und Anpassungen

For a gluten-free version, substitute the flour with a gluten-free blend. You can also add extra crunch by mixing toasted chopped almonds or pistachios into the crumble. Adjust sweetness by varying the sugar amounts slightly based on your taste preferences.

Serviervorschläge

Serve these lemon mousse cups chilled for a light and elegant dessert. Garnish with fresh berries, lemon zest curls, and mint leaves for a colorful finishing touch. Pair well with a glass of chilled Moscato or Prosecco to elevate the springtime vibe.
