Instructions
- 1
Prepare Dacquoise: Preheat oven to 170°C (340°F). Whisk egg whites with granulated sugar to stiff peaks. Fold in sifted powdered sugar, ground hazelnuts, and flour. Spread batter into an 18cm (7-inch) circle on parchment paper and bake for 15-18 minutes until lightly golden. Let cool, then trim to an 18cm disc.

Make Ganache Insert: Heat 100g heavy cream until simmering. Pour over chopped dark chocolate and let sit for 2 minutes, then whisk until smooth. Stir in cold butter until fully incorporated. Pour into a 16cm (6.3-inch) ring mold lined with plastic wrap and freeze for at least 4 hours, or overnight.

Prepare Praline Crunch: Melt the 50g milk chocolate. Stir in praline paste and feuilletine until well combined. Press evenly into another 16cm (6.3-inch) ring mold lined with plastic wrap. Freeze for at least 2 hours, or until firm.

Create Mousse: Bloom 2 sheets gelatin in cold water. Heat 75g heavy cream until simmering, then pour over 150g milk chocolate and 50g praline paste. Stir until smooth. Squeeze excess water from gelatin and stir into the warm chocolate mixture until dissolved. Let cool to room temperature (around 25°C / 77°F). Whip 250g cold heavy cream to soft peaks. Gently fold into the cooled chocolate mixture until fully incorporated.

Assemble Entremet: Place the 18cm dacquoise disc at the bottom of an 18cm (7-inch) cake ring or silicone mold. Pour about half of the chocolate hazelnut mousse over the dacquoise. Carefully unmold and place the frozen ganache insert on top of the mousse, pressing gently. Pour the remaining mousse over the ganache, ensuring it fills the sides. Finally, unmold and place the frozen praline crunch layer on top of the mousse. Smooth the top and freeze for a minimum of 6-8 hours, preferably overnight, until completely solid.

Prepare Mirror Glaze: Bloom 3 sheets gelatin in cold water. In a saucepan, combine granulated sugar, water, 100g heavy cream, and cocoa powder. Bring to a boil, stirring constantly, then remove from heat. Stir in the chopped dark chocolate until melted and smooth. Squeeze excess water from gelatin and stir into the warm glaze until dissolved. Use an immersion blender to emulsify, being careful not to incorporate air bubbles. Strain through a fine-mesh sieve and let cool to 32-35°C (90-95°F).

Glaze and Finish: Place the frozen entremet on a wire rack set over a baking sheet (to catch excess glaze). Pour the tempered mirror glaze evenly over the entire frozen entremet, ensuring full coverage. Let excess glaze drip off, then use an offset spatula to carefully transfer the entremet to a serving plate. Decorate as desired with roasted hazelnuts or chocolate shavings.

Thaw and Serve: Refrigerate the glazed entremet for 4-6 hours to thaw completely before serving. For clean slices, use a hot, dry knife, wiping it clean between each cut.
Baker's Tip
Freezing each component completely before assembly is paramount for a perfectly structured entremet. This ensures clean, distinct layers and prevents textures from blurring, resulting in a beautiful and professional finish.
Frequently Asked Questions
Can I make this entremet ahead of time?
Absolutely! Entremets are perfect for making in advance. You can assemble and freeze the entire cake (before glazing) for up to 2-3 weeks. Glaze it a day or two before serving, then thaw in the refrigerator.
My mirror glaze has bubbles or is too thick/thin. What went wrong?
Bubbles often result from over-blending or incorporating air; use an immersion blender at an angle and keep the head submerged. If the glaze is too thick, it might be too cold; warm it gently. If too thin, it's likely too warm or hasn't set enough; let it cool further to the recommended temperature before pouring.
What can I substitute for feuilletine?
Feuilletine provides a unique crispy texture, but if unavailable, you can use crushed cornflakes or even finely crushed digestive biscuits mixed with a little melted butter. The texture won't be identical, but it will still provide a pleasant crunch.
How do I ensure clean cuts when serving?
For pristine slices, ensure the entremet is fully thawed but still firm from refrigeration. Dip a long, sharp knife in very hot water, wipe it completely dry, and then make a single, clean cut. Repeat this process for each slice, re-heating and cleaning the knife every time.
