# What You'll Need:

→ 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

→ 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

→ Garnish

13 - 1 cup mixed fresh berries (raspberries, blueberries, strawberries)
14 - 2 tbsp white chocolate shavings (optional)
15 - Fresh mint leaves (optional)

# Method:

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, knead briefly, shape into a disc, wrap in plastic, and refrigerate for 30 minutes.
02 - Preheat oven to 350°F. Roll dough to 1/8-inch thickness and cut circles. Press dough into 6 tartlet pans (4-inch), trim excess. Prick bases with a fork, line with parchment, and fill with pie weights. Bake for 10 minutes, remove weights and parchment, then bake 5–7 minutes more until golden. Cool completely.
03 - Place chopped white chocolate in a heatproof bowl. Heat 1/2 cup heavy cream in a small saucepan until just simmering, then pour over chocolate. Let sit for 1 minute, then stir until smooth and glossy. Cool to room temperature.
04 - Beat egg whites with salt until soft peaks form. Gradually add sugar, beating until stiff, glossy peaks form.
05 - In a separate bowl, whip remaining 1/2 cup heavy cream to soft peaks.
06 - Gently fold whipped cream into cooled chocolate mixture until incorporated. Fold in egg whites and vanilla extract until fully combined and airy.
07 - Spoon or pipe mousse into cooled tartlet shells, smoothing tops. Refrigerate for at least 2 hours until set.
08 - Top each tartlet with fresh berries, white chocolate shavings, and mint leaves if desired. Serve chilled.

# Chef's Tips:

01 -
  • The mousse texture is impossibly light while still feeling luxuriously rich
  • These can be made ahead, leaving you free to enjoy your own gathering
02 -
  • Let the chocolate ganache cool completely before folding, or the whipped cream will deflate
  • Rotten egg whites will never reach proper peaks, so use room temperature fresh eggs
03 -
  • Use a kitchen scale for the dough because flour measurements vary wildly by volume
  • Room temperature egg whites whip up much faster and hold air better
