380 cm2 - 24 x 14 chocolate biscuit
Chocolate joconde biscuit
Preheat the oven to 170°C
Sift 5g of cocoa, 35g of icing sugar and 10g of flour together
Add 35g of ground almond
Melt 8g of butter
Add 1 egg white and 5g of sugar to a mixing bowl
In a bowl, whisk 75g of beaten eggs at maximum speed for 5 minutes until the mixture turns white
Gently fold in the dry ingredients and melted butter
Whip the egg white with the sugar and gently fold in with the spatula
Place the extendable frame set to 24 x 14 on a silicone mat and a perforated baking tray
Pour the mixture into the frame then bake for 12 minutes
Let it cool
Chocolate mousse
Whip 300g of whipping cream into whipped cream, gradually increasing the speed and set aside
Melt 200g of dark chocolate in a bain-marie to obtain a smooth and shiny texture
In a saucepan, add 22g of water and add 80g of sugar and bring to a boil
In your food processor's bowl, whisk 60g of egg yolk and 90g of whole egg at maximum speed
When the syrup reaches 114°C, reduce the food processor speed, pour the syrup the length of the bowl and immediately turn up to maximum speed for 3 minutes
Add the cooled melted chocolate and mix
Pour the chocolate sabayon over the whipped cream and mix gently with a spatula
Assembling the dessert
Pour the chocolate mousse over the biscuit
Set aside in freezer for at least 12 hours
Whipped vanilla ganache
The night before
Prepare the gelatine 15 minutes before starting
For the gelatine sheets, soak 1 sheet in VERY cold water
For the gelatine powder, weigh 2g, add 10g of cold water and let it stand in the fridge
Simmer 150g of double cream with the seeds from a vanilla pod
Melt 60g of white chocolate in a bain-marie
Add the gelatine to the hot cream, mix then pour it in three batches over the chocolate and mix with a whisk or spatula to fold it in
Add 105g of cold cream and mix evenly
Cover with clingfilm, in direct contact with the ganache's surface, and set aside in the fridge until the next day
D-day
Take the whipped ganache out of the fridge and pour the mix into the chilled bowl of your food processor
Whisk at medium speed for about 3 minutes to obtain a fairly thick texture; the ganache must be able to pass between the wires of the whisk. Make sure you don't whip the ganache for too long so it doesn't turn grainy
Add to a piping bag or Le Tube fitted with a plain round nozzle (10mm or 12mm)
Assembly
Take the dessert out of the freezer
Using a blowtorch or a hot cloth, remove the stainless steel frame
Flock immediately with a velvet glaze spray (optional)
Pipe small "Christmas trees" with the whipped vanilla ganache to give an impression of the forest on top of the dessert
Let it defrost for at least 6 hours in the fridge
Bring to room temperature 15 minutes before serving
