Instructions

1. Gelatin hydration

   Place the gelatin sheets in a bowl with 50 ml cold water and let soak for 5 minutes until fully rehydrated.

   Time: PT5M

2. Vanilla infusion in the cream

   Bring 300 ml of liquid cream to a boil, remove from heat, add the seeds and pods of the first 2 vanilla beans. Let infuse for 1 hour at room temperature.

   Time: PT1H10M

3. Preparation of the white ganache

   Warm 300 ml of liquid cream, dissolve the rehydrated gelatin (squeezed). Pour this hot mixture over the chopped white chocolate, stir until the chocolate fully melts. Add the remaining cold cream, stir, then place in the refrigerator for at least 4 hours to set.

   Time: PT15M

   Temperature: 82°C

4. Cooking the praline

   In a saucepan, bring to 118 °C 100 ml water with 200 g sugar. Add the whole almonds and hazelnuts, cook until a thin white film forms, then continue cooking until the mixture caramelizes slightly. Immediately pour onto a Silpat placed on a tray.

   Time: PT20M

   Temperature: 118°C

5. Praline setting

   Let the praline cool completely (about 30 minutes), then blend at high speed until a smooth paste is obtained. Reserve 120 g for the filling and keep the rest for the final glaze.

   Time: PT5M

6. Sponge preparation

   In a bowl, mix almond flour, brown sugar, the 4 whole eggs and a pinch of salt. Beat the egg whites to stiff peaks, gradually add 100 g granulated sugar to obtain a glossy meringue. Gently fold the meringue into the batter, then sift the flour and baking powder and fold them in by lifting. Add the vanilla extract and the 60 g chopped almonds/hazelnuts.

   Time: PT20M

7. Baking the sponge

   Pipe the batter into a piping bag, pipe a rectangle of 30 × 10 cm onto a sheet lined with parchment paper. Bake at 180 °C for 20 minutes. Let cool for 30 minutes on a rack.

   Time: PT20M

   Temperature: 180°C

8. Vanilla mascarpone cream

   Whisk the 4 egg yolks with 100 g sugar until the mixture whitens. Warm the vanilla-infused cream to 82 °C, dissolve the remaining gelatin (squeezed) in it. Slowly pour the hot mixture over the sugared yolks while whisking. Incorporate the mascarpone and let stand at room temperature.

   Time: PT15M

   Temperature: 82°C

9. Yule log assembly – first layer

   Cut the sponge to the size of the log mold. Spread half of the cooled white ganache over the sponge, smooth. Distribute 120 g praline over the ganache, spread lightly. Cover with the remaining white ganache. Place in the refrigerator for 1 hour to set.

   Time: PT30M

10. Final chocolate and praline glaze

    Melt 150 g dark chocolate, incorporate the remaining praline (about 80 g) and the crumbled feuilletine. Spread this glaze over the top of the sponge, let set for 15 minutes in the refrigerator.

    Time: PT15M

    Temperature: 45°C

11. Finishing and decoration

    Whip the remaining white ganache (about 3/4) until thickened, place in a piping bag with a Saint‑Honoré tip and pipe around the log to form a rosette. Decorate with the edible gold leaf. Place the log in the freezer for at least 7 hours (ideally overnight).
