# What you'll need:
→ For the Tartlet Shells
01 - 1 1/4 cups all-purpose flour
02 - 1/4 cup powdered sugar
03 - 1/4 tsp fine sea salt
04 - 1/2 cup cold unsalted butter, cubed
05 - 1 large egg yolk
06 - 2 tbsp cold water
→ For the White Chocolate Mousse
07 - 6 oz good-quality white chocolate, chopped
08 - 1 cup heavy cream, divided
09 - 2 large egg whites, room temperature
10 - 2 tbsp granulated sugar
11 - 1/2 tsp pure vanilla extract
12 - Pinch of salt
→ For Garnish
13 - 1 cup mixed fresh berries
14 - 2 tbsp white chocolate shavings
15 - Fresh mint leaves
# Directions:
01 - Pulse flour, powdered sugar, and salt in a food processor until combined. Add cold butter and pulse until mixture resembles coarse crumbs. Add egg yolk and cold water, pulsing until dough just comes together. Turn dough onto a lightly floured surface and knead briefly. Shape into a disc, wrap in plastic, and chill for 30 minutes.
02 - Preheat oven to 350°F. Roll dough to 1/8-inch thickness. Cut out circles and press into 6 (4-inch) tartlet pans. Trim excess dough. Prick bases with a fork, line with parchment, and fill with pie weights. Bake 10 minutes, remove weights and parchment, and bake 5–7 minutes more until golden. Cool completely.
03 - Place chopped white chocolate in a heatproof bowl. In a small saucepan, heat 1/2 cup heavy cream until just simmering. Pour over chocolate and let sit for 1 minute. Stir until smooth and glossy. Let cool to room temperature.
04 - In a clean bowl, beat egg whites with salt until soft peaks form. Gradually add sugar, beating to stiff peaks. In another bowl, whip remaining 1/2 cup cream to soft peaks.
05 - Gently fold whipped cream into cooled chocolate mixture, then fold in egg whites and vanilla until fully combined and airy.
06 - Spoon or pipe the mousse into cooled tartlet shells, smoothing the tops. Chill tartlets for at least 2 hours, or until set.
07 - Top each tartlet with fresh berries, white chocolate shavings, and mint leaves if desired. Serve chilled.
# Expert Suggestions:
01 -
- These tartlets make you look like a classically trained pastry chef with surprisingly simple techniques
- The contrast between crisp buttery shells and cloudlike mousse creates a dessert people never forget
02 -
- The chocolate ganache must reach room temperature before folding, otherwise your mousse will separate and turn grainy
- Overbeating the egg whites makes them difficult to fold in without deflating, stop as soon as stiff peaks form
03 -
- Brush the cooled shells with melted white chocolate before filling to create a moisture barrier that keeps them crisp for hours
- Room temperature egg whites whip up more voluminously and hold their structure longer than cold ones
