# How-to Steps:
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 refrigerate for 30 minutes.
03 - 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.
04 - Bake for 10 minutes, remove weights and parchment, and bake 5–7 minutes more until golden. Cool completely.
05 - 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.
06 - In a clean bowl, beat egg whites with salt until soft peaks form. Gradually add sugar, beating to stiff peaks.
07 - In another bowl, whip remaining 1/2 cup cream to soft peaks.
08 - Gently fold whipped cream into cooled chocolate mixture, then fold in egg whites and vanilla until fully combined and airy.
09 - Spoon or pipe the mousse into cooled tartlet shells, smoothing the tops.
10 - Refrigerate tartlets for at least 2 hours, or until set.
11 - Top each tartlet with fresh berries, white chocolate shavings, and mint leaves if desired. Serve chilled.
