03 - 1/4 tsp fine sea salt
04 - 1/2 cup cold unsalted butter, cubed

→ White Chocolate Mousse
07 - 6 oz good-quality white chocolate, chopped

13 - 1 cup mixed fresh berries

# How To Make It:
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.
02 - Turn dough onto a lightly floured surface and knead briefly. Shape into a disc, wrap in plastic, and chill for 30 minutes. 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.
03 - 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.
04 - Place chopped white chocolate in a heatproof bowl. Heat 1/2 cup heavy cream in a small saucepan until just simmering. Pour over chocolate and let sit for 1 minute. Stir until smooth and glossy. Let cool to room temperature.
05 - Beat egg whites with salt until soft peaks form. Gradually add sugar, beating to stiff peaks.
06 - Whip remaining 1/2 cup cream to soft peaks in a separate bowl.
07 - Gently fold whipped cream into cooled chocolate mixture, then fold in egg whites and vanilla until fully combined and airy.
08 - Spoon or pipe the mousse into cooled tartlet shells, smoothing the tops. Chill tartlets for at least 2 hours, or until set.
09 - Top each tartlet with fresh berries, white chocolate shavings, and mint leaves if desired. Serve chilled.
# Expert Suggestions:
01 -
- The contrast between crisp buttery shells and cloudlike mousse creates the most luxurious texture in every single bite
- These tartlets look impressively elegant but actually come together with techniques any home cook can master
02 -
- Room temperature egg whites whip up much better than cold ones, so take them out of the fridge at least 30 minutes before you start
- Overbaking the tartlet shells will make them tough, so pull them out as soon as you see golden edges
03 -
- Brush the cooled tartlet shells with a thin layer of melted white chocolate before filling to create a moisture barrier that keeps the shells crisp longer
- If your kitchen is warm, place your mixing bowl and beaters in the freezer for 10 minutes before whipping the egg whites for better volume
