Pastry cream
Bloom the gelatine in cold water. Heat the milk and pour, together with the boiling cream, over the beaten mixture of sugar, powdered cream, flour and egg yolks. Boil for 2 minutes, then add the cocoa butter. Squeeze the gelatine, and add to the mixture, then the butter and lastly the mascarpone. Mix and cool rapidly.
Chestnut cream
* Make a custard with the cream, sugar and egg yolks, add the powdered gelatine when hot and pour over the mascarpone, pastry cream and chestnut paste mixture. Mix and keep in a cool place.
Hazelnut praline
Roast the hazelnuts at 150°C for 30 minutes. Cook the sugar with the water at 110°C to form caramel and then caramelize the hazelnuts well to obtain a thick praline.
Chestnut crunch

Soft chestnut biscuit
Beat the butter and the chestnut paste. Beat the egg yolks and sugar 1 until pale. Sieve the flour and starch. Beat the egg whites and stiffen with sugar 2. Mix the egg yolks with the butter/chestnut paste mixture. Fold in the beaten egg whites gently and then the flour and starch; stop mixing once the mixture is homogeneous. Roll out the dough and make thin strips, cover with marrons glacés. Cook at 175°C for 13 minutes (850 g/tray). Cut discs to size.
Chestnut jelly
