Pour the hazelnuts onto a baking tray and place in the oven at 150°C for 15 minutes. Pour the caster sugar into a saucepan and make a caramel. Pour onto a sheet of greaseproof paper and leave to cool. Place the hazelnuts, which have been rubbed to remove as much of the skin as possible, and the caramel, cut into pieces, in the bowl of a blender and blend until the praline is obtained.
Hazelnut biscuit ✔35g icing sugar ✔1 egg ✔35g hazelnut powder ✔10 g butter ✔7 g flour ✔1 egg white
Melt the butter. In a bowl, mix the whole egg with the icing sugar. Add the hazelnut powder, flour and melted butter. Mix well. In another bowl, beat the egg whites with a mixer. Gently fold into the mixture using a pastry blender. Pour the biscuit dough onto a baking tray lined with baking paper. Bake the biscuit for approximately 10 minutes at 170°C. Remove the biscuit from the oven and leave to cool before peeling it from the paper and cutting it out using the cookie cutter supplied with the tin.
Soften the gelatine leaves in a bowl of cold water. Heat the pear purée (blended ripe pears or blended pears in syrup) in a saucepan. Remove from the heat and add the gelatine, wrung out and softened, stirring well. Set aside. Whip the cold cream with a mixer, adding the icing sugar. Add the cooled pear purée.
