Instructions
Vanilla milk infusion (ganache)
Split the two vanilla beans, scrape the seeds and place them in the milk. Bring to a boil, remove from heat, cover and let infuse for 1 hour.
Time: PT1H5M
Temperature: 100°C
Gelatin hydration
Place the gelatin sheets in a bowl of cold water for 5 minutes to soften.
Time: PT5M
Ganache mixing
Warm the infused milk, remove the bean pod, add the squeezed gelatin and stir until fully dissolved. Pour the hot milk over the white chocolate cut into pieces and stir until a smooth ganache forms.
Time: PT5M
Temperature: 45°C
Incorporating the cream
Add the cold whole liquid cream to the ganache, whisk gently until homogeneous, then cover and place in the refrigerator for at least 4 hours (ideally overnight).
Time: PT5M
Vanilla milk infusion (insert)
Repeat the milk infusion with the two vanilla beans, bring to a boil then let infuse for 1 hour.
Time: PT1H5M
Temperature: 100°C
Hydration of the second gelatin
Soften a new portion of gelatin sheets in cold water for 5 minutes.
Time: PT5M
Preparation of vanilla‑mascarpone crème
Whisk the egg yolks with the sugar until pale. Gradually pour the hot milk (without the bean) while whisking. Return everything to the saucepan and heat to 82°C, monitoring with a thermometer. Off the heat, incorporate the squeezed gelatin then the mascarpone, mixing until smooth.
Time: PT10M
Temperature: 82°C
Molding the insert
Pour the crème into the insert mold lined with RODOIDE film, smooth the surface and place in the freezer for 1 hour to set.
Time: PT1H
Adding the caramel pearls
After 1 hour, distribute the caramel pearls over the still slightly soft crème, then refreeze for at least 2 more hours.
Time: PT5M
Roasting the pecan nuts
Heat a pan over medium heat, add the pecan nuts and dry‑toast for 5 minutes, stirring constantly until golden. Let cool to room temperature.
Time: PT5M
Temperature: 180°C
Whipping the ganache
Remove the ganache from the refrigerator and whisk on low speed until thickened (about 5 minutes).
Time: PT5M
Assembling the Yule log – first layer
Pour a first layer of ganache into the silicone log mold, gently place the insert in the center, then cover completely with the remaining ganache. Smooth the surface.
Time: PT5M
Preparing the base biscuit
Blend the toasted pecan nuts, the petit beurre cookies and the melted butter until a homogeneous paste forms. Spread this mixture over the set ganache and press firmly with the back of a spoon.
Time: PT10M
Final freezing
Place the assembled log in the freezer overnight (minimum 12 hours) so the layers hold firmly.
Time: PT12H
White chocolate glaze
Melt the white chocolate in a bain‑marie or microwave (5 minutes), then spread it onto a sheet of parchment paper to form a smooth slab. Let set for a few minutes then cut into long strips.
Time: PT5M
Temperature: 45°C
Coating the log
Place the white chocolate strips on the cooled log, lightly adhere them with a drizzle of melted chocolate and smooth the edges. Let set at room temperature or in the refrigerator for 5 minutes.
Time: PT5M
Decorative finishing
Cut the remaining white chocolate into pieces, melt them slightly and attach to the log to create decorations. Sprinkle with white sprinkles for a “snow” effect if desired.
Time: PT10M
Temperature: 45°C

Chef Tips from the Video

Troubleshooting
The ganache separates or becomes grainy
Return the ganache to a bain‑marie over low heat, whisking continuously until homogeneous.
The crème coagulates and forms lumps
Remove immediately from heat as soon as 82°C is reached, whisk vigorously and incorporate the gelatin off the heat.
The pecan nuts are bitter
Do not let them burn; remove from heat as soon as they are golden and let them cool quickly.
The white chocolate does not set or cracks
Melt at low temperature, avoid overheating and let the chocolate cool slightly before applying.
