Preparation

Hazelnut crumbs

Mix all ingredients to form a crumble.

Spread onto a baking tray and bake at 155°C for 15 minutes.

Hazelnut crunch

Melt the dark chocolate and the hazelnut paste.

Mix in the crumbs, feuilletine, and sea salt.

Place the mixture in a ring lined with baking paper.

Set aside.

Parmigiano Reggiano génoise

Heat the eggs and sugar to 40°C and beat until frothy.

Sift the flour and corn starch over the top.

Grate the Parmigiano Reggiano into the milk with the trehalose and heat to 40°C.

Stir well.

Pour the batter into 15 cm moulds.

Bake for 30 to 35 minutes at 160°C.

Allow to cool and cut into 2 layers of 0.7 cm.

Fig marmalade

Simmer the fig purée until it is reduced to 96 g.

Then add the Kelulut honey and the glucose-pectin mixture.

Boil for 30 seconds.

Add the lemon purée, fresh figs, and vanilla pod.

Set aside.

Truffle honey syrup

Mix all the ingredients together and spread on the génoise.

Brie and truffle interior

Mix the milk and the brie and heat to 80°C.

Add the gelatine mixture and leave to cool to 35°C.

Add the black truffle paste and mix everything with xanthan gum.

Dark chocolate mousse

Mix the Stand & Overrun (1), milk, egg yolk, and sugar and cook to 82°C.

Add the chocolate.

Stir and allow the mixture to cool to 38°C.

Whip the Stand & Overrun (2) until firm but not stiff and fold into the previous mixture.

Piping mixture

Melt the cocoa butter.

Add the white chocolate and dark cocoa powder.

Stir everything together.

Nut and chocolate interior

Melt all the ingredients until you obtain a homogeneous mass.

Pour into a silicone mould (Sf006).

Freeze.

Whipped truffle ganache

Melt the chocolate.

Add the rest of the ingredients.

Emulsify and leave to stand for a night.

Whip the ganache until firm but not stiff and pipe into a silicone mould (Sf005).

Add the nut and chocolate interior.

Freeze.

Assembly

Construct a sandwich-like interior by spreading fig marmalade between two layers of génoise with Parmigiano Reggiano.

Freeze.

Add a layer of brie and truffle and freeze again.

Construct the entremets: pour 350 g of dark chocolate mousse into a silicone eclipse mould.

Add the interior, followed by another 20 g of chocolate mousse.

Finish with the hazelnut crunch.

Remove the entremets from the mould and cover with the dark piping mixture.
