Instructions

Prepare the Mousse: Beat the egg yolks and granulated sugar together until pale and creamy. In a small saucepan, heat 1/4 cup of heavy cream until warm but not boiling. Slowly combine the warm cream with the yolk mixture and cook over low heat, stirring constantly until the mixture thickens. Remove from heat and stir in the chopped white chocolate until fully melted and smooth. Allow to cool.
Whip the Cream: In a clean bowl, whip the remaining 3/4 cup of heavy cream until medium-stiff peaks form. Gently fold the whipped cream into the cooled white chocolate mixture to keep the mousse light and airy.
Chill the Mousse: Cover and refrigerate the mousse mixture until ready to fill the tart shell, allowing it to firm up slightly for better texture.
Make the Tart Shell Dough: Preheat the oven to 190ºC (374ºF). In a food processor, combine the all-purpose flour, salt, cayenne pepper, and cinnamon. Add cold butter cut into small pieces and pulse until the mixture resembles coarse crumbs. Add the egg and pulse until the dough just comes together. Shape into a disk, wrap it in plastic wrap, and chill for at least 30 minutes.
Bake the Tart Shell: Roll out the chilled dough on a lightly floured surface and fit it into tart tins. Prick the base with a fork, then line with parchment paper and fill with baking weights or dried beans for blind baking. Bake for 10 minutes, remove the weights and paper, then bake for an additional 5 minutes or until the crust is golden brown. Allow to cool completely.
Assemble the Tart: Spoon the prepared white chocolate mousse into the cooled tart shells, smoothing the tops. Refrigerate the filled tarts for 1 to 2 hours or until the mousse is set.

Notes

Ensure the butter is very cold when making the tart dough to achieve a flaky crust.
Do not overwhip the cream to avoid turning it into butter. Medium-stiff peaks are ideal.
The cayenne pepper adds a subtle warmth to the tart shell; adjust to taste or omit for a milder flavor.
Use high-quality white chocolate for the best flavor and smooth texture.
Allow the tart shells to cool fully before filling to prevent the mousse from melting.
