Instructions

1. Poach the pears

   Peel the pears, halve them, then quarter each half. In a saucepan combine water, 150 g sugar, lemon juice, the scraped seeds of the vanilla bean, the split vanilla pod and the cinnamon stick. Bring to a simmer, stir until sugar dissolves, then add the pear quarters. Simmer gently for about 30 minutes until the pears are translucent and tender (test with a knife tip).

   Time: PT40M

2. Cool and reserve syrup

   Remove the pan from heat, discard the cinnamon stick and vanilla pod, and let the poached pears cool in the syrup. Transfer the pears to a bowl, keep the syrup for later use, and set the pears aside.

   Time: PT5M

3. Puree half of the poached pears

   Place about 200 g of the poached pears (including some syrup) in a blender and blend until completely smooth. Set aside the smooth puree; keep the remaining pear pieces for decoration.

   Time: PT5M

4. Slice pears for decoration

   Cut roughly 250 g of the poached pears into bite‑size pieces and set aside in a separate bowl.

   Time: PT5M

5. Make biscuit dough – yolk mixture

   In a large bowl whisk together 75 g yellow caster sugar and the 4 egg yolks until the mixture becomes pale, thick and mousse‑like (about 3–4 minutes).

   Time: PT5M

6. Whip egg whites

   In a clean bowl, whisk the 4 egg whites until foamy, then gradually add 40 g sugar while continuing to whisk until stiff, glossy peaks form.

   Time: PT5M

7. Combine yolk and white mixtures

   Fold about one‑third of the whipped egg whites into the yolk mixture to lighten it, then gently fold in the remaining whites until just incorporated. The batter should stay airy and glossy.

   Time: PT5M

8. Incorporate flour and starch

   Sift the 50 g flour and 20 g potato starch over the batter and fold very gently until just combined, taking care not to deflate the mixture.

   Time: PT5M

9. Pipe and bake the ladyfingers

   Fit a piping bag with a 10 mm plain tip, fill with the batter and pipe 9‑cm long strips onto parchment‑lined baking sheets, spacing them a little apart. Dust generously with powdered sugar. Bake in a pre‑heated 170 °C convection oven for 15–18 minutes, until very lightly golden.

   Time: PT23M

   Temperature: 170°C

10. Cool biscuits

    Allow the baked biscuits to cool completely on the sheets before removing them; this prevents breakage.

    Time: PT10M

11. Prepare speculoos‑wafer crunch

    In a bowl crumble the speculoos biscuits and chocolate wafers (crêpes dentelle) into fine crumbs. In a microwave‑safe bowl melt 80 g butter with 100 g dark chocolate (crunch portion) in 30‑second intervals, stirring between each, until smooth. Combine the melted butter‑chocolate with the crumbs, mixing until a homogeneous paste forms.

    Time: PT10M

12. Set crunch layer in the cake mold

    Line a 20 cm × 8 cm cake (or loaf) pan with two layers of cling film. Press a thin layer of the crunch mixture onto the bottom of the pan, smoothing with the back of a spoon. Refrigerate for 5 minutes to firm.

    Time: PT10M

13. Rehydrate gelatin

    Place the 2 gelatin sheets in a bowl of cold water and let them soak for 10 minutes until soft.

    Time: PT10M

14. Heat half of the pear puree with sugar and vanilla

    In a small saucepan combine half of the smooth pear puree (≈100 g), 30 g sugar and the scraped vanilla seeds. Heat gently, stirring, until it reaches a light boil, then remove from heat.

    Time: PT5M

15. Add gelatin and remaining puree

    Squeeze excess water from the gelatin sheets, add them to the hot pear mixture and stir until fully dissolved. Then stir in the remaining pear puree, mix well and let the mixture cool to room temperature (about 15 minutes).

    Time: PT15M

16. Whip the cream

    In a clean bowl, whip 80 ml of heavy cream with a pinch of vanilla powder until soft peaks form.

    Time: PT5M

17. Create the pear mousse

    Fold the whipped cream into the cooled pear‑gelatin mixture using a spatula, moving gently until fully incorporated and the mousse is smooth and glossy.

    Time: PT5M

18. Assemble the bûche – first biscuit layer

    Place the first row of ladyfinger biscuits along the length of the prepared pan, trimming the bases slightly so they sit flush. Brush the biscuits lightly with the reserved poaching syrup using a pastry brush (only the bottom and very thinly on the sides).

    Time: PT5M

19. Add mousse and pear pieces

    Spread a 2 cm thick layer of pear mousse over the biscuit base, smooth with an offset spatula. Evenly distribute the reserved poached pear pieces into the mousse, pressing gently. Add a thin second layer of mousse on top and smooth again.

    Time: PT10M

20. Add second biscuit layer and repeat

    Place the second trimmed biscuit layer on top of the mousse, press lightly, brush with a little more syrup, then spread another thin mousse layer, add more pear pieces, and finish with a final thin mousse coat. Smooth the surface.

    Time: PT10M

21. Freeze the assembled bûche

    Cover the pan with cling film and place it in the freezer for at least 1 hour (overnight preferred) to set the mousse firmly.

    Time: PT1H

22. Prepare the chocolate ganache

    Finely chop 200 g dark chocolate (70 % cacao) and place in a bowl. In a saucepan bring 70 ml heavy cream to a boil, then pour the hot cream over the chocolate in three batches, stirring after each addition until smooth. Add the remaining 80 ml cold cream, stir to a glossy consistency. Let cool to room temperature, then refrigerate for 30 minutes until thickened.

    Time: PT15M

    Temperature: 100°C

23. Whip the ganache lightly

    Remove the ganache from the fridge and whisk with a hand mixer for a few seconds until it becomes silky and pourable (do not over‑whisk or it will grain).

    Time: PT5M

24. Make pear chips

    Using a mandoline, slice a fresh pear (or leftover poached pear) into very thin rounds. Lay the slices on a parchment‑lined tray, dust lightly with powdered sugar, and bake in a 150 °C oven for 20–25 minutes until crisp and golden. Cool completely.

    Time: PT30M

    Temperature: 150°C

25. Unmold and finish the bûche

    Remove the frozen bûche from the pan, peel away the cling film, and place on a serving platter. Spread a thin layer of ganache over the top and sides, smoothing with a spatula. Pipe small chocolate ganache pearls on the summit, drizzle with extra ganache, and garnish with pear chips, poached pear pieces, and optional mascarpone chantilly (80 ml cream + 30 g mascarpone + 10 g powdered sugar + vanilla powder, whipped).

    Time: PT15M

26. Final chill before serving

    Re‑cover the decorated bûche and refrigerate for at least 1 hour to set the ganache. Slice with a hot knife for clean cuts and serve.

    Time: PT1H

Chef Tips from the Video

• Use parchment paper on the baking sheets for easy biscuit removal
• A silicone brush gives better control when brushing syrup onto biscuits
