Full Recipe:

Ingredients

For the White Chocolate Mousse:

• 2 egg yolks

• 2 tablespoons granulated sugar

• 1 cup heavy cream

• 80 grams white chocolate

For the Pastry:

• 350 grams all-purpose flour

• 125 grams unsalted butter (cold, cut into small squares)

• 125 grams sugar

• 2 eggs + 1 egg yolk

• Pinch of salt

• 1/4 teaspoon cayenne pepper

• 1/4 teaspoon cinnamon

For the Egg Wash:

• 1 egg

• 1 teaspoon milk

Directions

1. Prepare the White Chocolate Mousse Base:
   Beat the egg yolks and sugar together in a bowl until pale. Heat ¼ cup of cream in a double boiler, then pour it over the egg yolk mixture. Stir to combine, then return the mixture to heat and cook until it thickens. Pour the mixture over broken white chocolate pieces and stir until the chocolate melts completely. Let it cool thoroughly.

2. Whip the Cream and Combine:
   In a separate bowl, whip the remaining cream until stiff peaks form. Gently fold the whipped cream into the cooled chocolate mixture, taking care not to deflate the air from the whipped cream. Refrigerate until ready to use.

3. Make the Pastry:
   Preheat the oven to 374°F (190°C). In a food processor, combine the flour, salt, cayenne pepper, and cinnamon. Add the cold butter and pulse until the mixture resembles breadcrumbs. Add the sugar, eggs, and egg yolk, and pulse just until the dough comes together.

4. Chill and Roll the Dough:
   Turn the dough out onto a dry surface and knead it until firm. Wrap it in parchment paper and refrigerate for at least 1 hour. Once chilled, roll out the dough and cut it to fit your tart tin or muffin tray.

5. Blind Bake the Pastry:
   Line the pastry with baking paper and add weights or beans. Bake for 10 minutes, then remove the paper and weights and bake for an additional 5 minutes until golden. Let the tart cases cool on a wire rack.

6. Assemble the Tartlets:
   Once the pastry has cooled, spoon the white chocolate mousse into each tart shell. Optionally, decorate with fresh fruit or a sprinkle of cinnamon and icing sugar.

A Velvety White Chocolate Mousse Filling

At the heart of this tart is the white chocolate mousse, which provides a delicate sweetness and a wonderfully creamy texture. The mousse is made by first preparing a custard base with egg yolks and sugar, then mixing it with melted white chocolate for an extra dose of richness. The egg yolks create a smooth texture, while the white chocolate gives the mousse its signature velvety creaminess. Once this mixture is allowed to cool, it is folded together with freshly whipped cream to create an airy, light mousse that still feels rich and indulgent.

The subtle flavor of the white chocolate is the perfect contrast to the spiced pastry crust, and the whipped cream adds a beautiful lightness that makes the mousse feel luxurious without being overwhelming. When chilled, the mousse firms up just enough to hold its shape while still remaining soft and silky on the palate.

The Pastry Crust: Buttery with a Hint of Spice

The pastry crust for this tart is what takes it from a standard dessert to something truly special. Made with a blend of all-purpose flour, cold butter, and a touch of sugar, the crust is rich, buttery, and slightly crumbly. What makes this crust truly unique, however, is the addition of cinnamon and cayenne pepper. The cinnamon adds a warm, aromatic depth to the flavor, while the cayenne pepper introduces a subtle heat that perfectly complements the sweetness of the white chocolate mousse.

This slightly spicy crust creates a beautiful balance of flavors, with the warmth of the spices providing a nice contrast to the sweetness of the filling. The crust is tender, crisp, and buttery, and it holds the mousse filling beautifully, making each bite a harmonious combination of rich and delicate textures.

The Perfect Pastry Crust Technique

Making the pastry for this tart requires careful handling to ensure it’s light, crisp, and buttery. The dough is prepared in a food processor, where the flour, spices, and butter are pulsed together until they resemble breadcrumbs. This ensures that the butter is evenly distributed throughout the flour, creating a tender texture when baked.

Once the dough is combined, it is chilled to help the fats set, which makes rolling out the dough easier and prevents it from shrinking during baking. After the dough is rolled out and placed in the tart tin or muffin tray, it is blind-baked to ensure it holds its shape and achieves a golden-brown color. Blind baking also ensures that the crust remains crisp even when filled with the creamy white chocolate mousse.

Assembling the Tart: A Beautiful Presentation

Assembling the tart is a simple but elegant process. Once the pastry shells have cooled, the white chocolate mousse is spooned into each tart shell. The mousse is light and fluffy, creating a beautiful contrast to the crisp, buttery crust. To add an extra touch of elegance, the tarts can be decorated with fresh fruit like raspberries, strawberries, or blueberries, or even a sprinkle of cinnamon or powdered sugar for a festive look.

The result is a dessert that’s visually stunning as well as delicious. The golden-brown pastry shell and creamy white chocolate mousse are a classic pairing, and the tart’s simple yet elegant appearance makes it the perfect dessert for a special occasion or dinner party.

Serving Suggestions and Pairings

The Rich White Chocolate Mousse Tart is an indulgent dessert that stands beautifully on its own, but it can also be paired with a variety of accompaniments. For a light and refreshing contrast to the rich mousse, serve the tart with fresh berries, a dollop of whipped cream, or a scoop of vanilla ice cream. A drizzle of raspberry or chocolate sauce can also add an extra layer of flavor to the tart, enhancing its indulgence even further.

This tart pairs wonderfully with a variety of beverages, from a rich cup of coffee or espresso to a light, crisp glass of white wine or champagne. The combination of the tart’s creamy mousse and buttery pastry with a refreshing drink will elevate the entire dessert experience.

Nutritional Information

While the Rich White Chocolate Mousse Tart is a decadent treat, it’s important to enjoy it in moderation due to its rich ingredients. A whole tart yields approximately 2700-3000 calories, and each serving (depending on portion size) will provide around 40-50 grams of protein, 160-180 grams of fat, and 280-300 grams of carbohydrates. The high fat content comes from the butter in both the pastry crust and the mousse, contributing to the tart’s rich, indulgent texture.

Although it is a rich dessert, the White Chocolate Mousse Tart provides some nutritional benefits, such as protein and a small amount of calcium from the cream and eggs. The cinnamon and cayenne pepper in the pastry may also offer a touch of antioxidant properties, although the primary purpose of these spices is to enhance the flavor profile.
