Preparation
Hazelnut praliné
Caramelise the sugar with the vanilla pod.
Add the hot roasted hazelnuts.
Pour onto baking paper and leave to cool.
Remove the vanilla pod.
Blend to a smooth praliné.
Italian buttercream with hazelnut
Bring the sugar with the water to a boil at 120°C and make an Italian meringue with the egg whites.
Beat until the meringue has cooled.
Beat the Debic Butter Constant until it is airy, together with the coffee extract and the hazelnut paste.
Mix the butter mixture in 3 parts in the egg white.
Coffee ganache montée
Roast the coffee beans in the oven at 160°C for 5 minutes.
Add them to half of the cold Debic Stand & Overrun and allow to infuse for 1 hour.
Bring the cream to a boil, pass through the conical sieve and melt the gelatin into it.
Make a ganache with the white chocolate.
Add the coffee liqueur and mix finely with the hand mixer.
Leave to stand in the refrigerator overnight, then beat to the required consistency.
Chocolate crumble
Mix the butter, the brown sugar, the salt and the ground almonds to a smooth dough.
Then mix in the sifted flour and the cocoa powder to form a crumbly structure.
Bake in rings (6 cm diameter) at 160°C for 25 minutes.
Hazelnut praliné crumble
Mix the crumble with the feuilletine.
Melt the chocolate and add the hazelnut paste, the hazelnut praliné and the salt.
Mix all the ingredients together.
Hazelnut meringue
Mix the egg white with the sugar and heat to 50°C.
Beat until light and airy.
Mix the hazelnut powder with the potato starch and add to the meringue.
Form circles measuring 7 cm, sprinkle with roasted broken hazelnuts and bake at 140°C for 45 minutes.
Glaze
Bring the water, sugar, and glucose to the boil at 103°C.
Add the gelatine mixture and the condensed milk.
Melt the chocolate in it and mix with the hand mixer to form a nice emulsion.
Add the coffee powder.
Assembly
Pipe 10 g of hazelnut praliné into a round mould with a flat bottom and place in the freezer.
Roll the crumble out between two sheets of plastic foil and freeze it.
Cut out with a 7 cm ring.
Fill a round 10 cm mould with a thin layer of Italian buttercream and press the frozen hazelnut praliné into it.
Now half fill the mould and press the hazelnut meringue strip into it.
Completely fill the mould with the buttercream and press a slice of crumble on top.
Freeze.
Heat the glazing at 31°C and mix finely with the hand mixer.
Glaze the pastries.
Pipe a large dollop of whipped coffee ganache on the tartlet.
Warm an ice-cream scoop and press in the middle of the ganache.
Fill the hole with a little hazelnut praliné.
