White Chocolate Raspberry Mirror Entremet
Ingredients
For the Almond Biscuit Base:
2 large egg whites
¼ cup granulated sugar
½ cup almond flour
¼ cup powdered sugar
1 tbsp all-purpose flour
For the Raspberry Gelée Insert:
2 cups fresh or frozen raspberries
¼ cup granulated sugar
1 tbsp lemon juice
1 ½ tsp powdered gelatin (bloomed in 2 tbsp cold water)
For the White Chocolate Mousse:
6 oz high-quality white chocolate, finely chopped
1 cup heavy whipping cream (divided)
1 tsp vanilla bean paste
1 tsp powdered gelatin (bloomed in 1 ½ tbsp cold water)
For the White Chocolate Mirror Glaze:
1 cup sugar
½ cup water
½ cup sweetened condensed milk
1 tbsp powdered gelatin (bloomed in ¼ cup cold water)
1 cup high-quality white chocolate chips
Instructions
Step 1: The Raspberry Gelée
In a small saucepan, combine the raspberries, sugar, and lemon juice. Cook over medium heat until the berries break down.
Press the mixture through a fine-mesh sieve to remove the seeds.
Stir the bloomed gelatin into the warm raspberry purée until completely dissolved.
Pour the mixture into a rectangular silicone insert mold (smaller than your final cake size) and freeze for at least 2 hours until solid.
Step 2: The Almond Biscuit
Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
Whip the egg whites and granulated sugar to stiff peaks. Gently fold in the almond flour, powdered sugar, and all-purpose flour.
Spread the batter into a thin rectangle on the baking sheet and bake for 10–12 minutes until slightly golden. Let cool, then cut into a rectangular strip slightly smaller than your main mold.
Step 3: The White Chocolate Mousse
Heat ¼ cup of the heavy cream until simmering, then pour it over the chopped white chocolate and bloomed gelatin. Stir until completely smooth and melted. Stir in the vanilla bean paste and let cool to room temperature.
Whip the remaining ¾ cup of heavy cream to medium peaks, then gently fold it into the cooled white chocolate mixture.
Step 4: Assembly
Pour about two-thirds of the white chocolate mousse into the bottom of a rectangular silicone entremet mold.
Gently press the frozen raspberry gelée block into the mousse.
Cover with the remaining mousse, then top with the rectangle of almond biscuit, pressing it down slightly so it sits flush with the top of the mold.
Freeze the entire mold overnight (it must be rock-solid to glaze successfully).
Step 5: The Mirror Glaze & Presentation
Bring the sugar, water, and condensed milk to a boil in a saucepan. Remove from heat and stir in the bloomed gelatin until dissolved.
Pour the hot liquid over the white chocolate chips, let sit for 1 minute, and use an immersion blender to make it perfectly smooth (keep the blender submerged to avoid air bubbles). Strain and let cool to roughly 90°F (32°C).
Unmold the frozen cake onto a wire rack over a tray. Pour the mirror glaze evenly over the frozen cake.
Transfer to your modern marble platter and garnish with fresh raspberries, blackberries, a chocolate curl, and a sprinkle of crushed hazelnuts. Let thaw in the fridge for 2 hours before slicing.
Creating a White Chocolate Raspberry Mirror Entremet is a rewarding challenge that combines multiple pastry techniques into one beautiful dessert. From my experience, using high-quality white chocolate makes a significant difference in both taste and texture, especially for the mousse and mirror glaze. When folding the whipped cream into the white chocolate mixture, I find that folding gently but thoroughly ensures a light, airy mousse without deflating it. For the raspberry gelée, straining the purée carefully is key to a smooth texture free of seeds, which enhances the eating experience. I personally prefer using fresh raspberries when in season, as they add a vibrant aroma, but frozen raspberries work well too and allow for year-round preparation. The almond biscuit provides a subtle nutty flavor that complements the tartness of the raspberry and the sweetness of the white chocolate. One tip for the mirror glaze: ensure it is cooled to about 90°F before pouring over the entremet. Too hot and it will melt the mousse, too cool and it won't spread smoothly. Using an immersion blender helps achieve a silky texture and eliminates air bubbles, giving your glaze that flawless mirror finish. Assembling the entremet the day before serving is ideal; freezing it overnight helps firm up the layers and enables a smooth glaze application. Letting the cake gradually thaw in the fridge after glazing preserves its texture and flavor balance. Garnishing with fresh raspberries, blackberries, and a sprinkle of crushed hazelnuts adds elegant texture and visual appeal, while also introducing complementary flavors to enhance this sophisticated dessert. Making this entremet at home is an impressive way to elevate your baking skills and delight anyone who tastes it.
