Spread the pistachios on a baking tray and bake at 150°C for 15 minutes. In a saucepan, add the caster sugar and make a caramel. Pour onto a sheet of baking paper and leave to cool. Place the pistachios and the chopped caramel in the bowl of a food processor and blend until you have a praline.
Mix the praline, melted white chocolate and crumbled crêpes dentelles. Roll out between two sheets of baking paper and place in the freezer for a few minutes. Cut into rectangles to fit your tin. Place in the freezer.

The next day, turn the desserts out of their moulds and immediately apply the white velvet spray.
I placed the dessert on my serving plate. I arranged some small white chocolate eggs on top. I served the dessert with red berries.
