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

→ Garnish
13 - 1 cup mixed fresh berries

# Step-by-Step Instructions:
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 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, then bake 5-7 minutes more until golden. Cool completely.
05 - Place chopped white chocolate in a heatproof bowl. Heat 1/2 cup heavy cream until just simmering, then pour over chocolate. Let sit for 1 minute, then stir until smooth and glossy. Cool to room temperature.
06 - Beat egg whites with salt until soft peaks form. Gradually add sugar, beating to stiff peaks.
07 - Whip remaining 1/2 cup heavy 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. Refrigerate for at least 2 hours until set.
10 - Top each tartlet with fresh berries, white chocolate shavings, and mint leaves if desired. Serve chilled.
# Tips from hearthlykitchen:
01 -
- The texture is impossibly light, like eating a sweet cloud that just happens to hold its shape beautifully in a crisp buttery shell
- They look like something from a French patisserie but come together with surprisingly simple techniques
02 -
- If your chocolate seizes and turns grainy, don't panic—whisk in a teaspoon of warm cream one drop at a time until it smooths out again
- 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
03 -
- Use a kitchen scale for the ingredients, especially the chocolate and flour—baking is chemistry and precision gives you consistent, perfect results every time
- When folding the whipped cream and egg whites into the chocolate, use a silicone spatula and fold gently to preserve all that air you've whipped in
