250g mascarpone
300g full cream, minimum 30% fat

METHOD

Pie crust
Beat the butter in a mixing bowl or in a food processor bowl until it becomes soft. Add the icing sugar and hazelnut powder and mix. Add the egg and salt and mix until smooth. Add the flour and mix briefly, then place the dough in cellophane for at least an hour in the refrigerator

Take your dough out of the fridge and roll out on a floured work surface. Roll out your dough on your rolling pin and roll it out on your pie cutter. Press the dough against the edges of the cutter with your finger to form a right angle and slightly raise the edges with your thumb and forefinger. Place your dough in the refrigerator for at least an hour or ideally overnight. Bake your pie crust in a preheated oven at 160° for 25 to 30 minutes.

Chocolate-coffee crémeux
Melt your chocolate in a bain-marie, At the same time, heat your cream with the honey and instant coffee, Once starts to boil, pour it over your melted chocolate in three stages, stirring between each stage. Place the crémeux in the fridge for 30 minutes. Once your crémeux has cooled, pour it over your pie crust and set aside until the next step.

Sponge fingers
Whip your egg whites until they are frothy and add the sugar then continue to whip until you have a nice meringue, Add the 30g of egg yolk to your egg whites and mix gently, Now you can add your sifted flour and starch and mix gently with a spatula. Prepare your mixture with a smaller diameter than your pie and bake for 20 minutes at 200°.

Tiramisu cream
In a mixing bowl or food processor, beat the egg yolks, sugar and vanilla powder until they double in size. Add the mascarpone and whisk until the mixture is smooth, Place to one side. Whip your cream until firm and add your vanilla cream and mascarpone mixture to your whipped cream, mixing with a whisk until smooth.

Assembly
Pour a long espresso and set it aside in a dish. Place your sponge fingers on your chocolate pie crust. Drizzle with coffee. Cover your sponge cake with a good layer of tiramisu cream. Fill a piping bag fitted with a 16mm fluted tip and pipe the top of your tart. Sprinkle generously with unsweetened cocoa powder.
