Preparation

Recipe for a 60 x 20cm baking sheet

Remove the top crust from the baked sponge cake and cut into two layers. Prepare the syrup and dip one of sponge layers to make the base layer. Soften the roasted nuts in a water bath and spread over the base sponge. Prepare the halva mousse. Whip the cream and separately mix water, halva paste and stabiliser. Gently mix in the whipped cream. Spread 3/4 of the prepared mousse over the hazelnuts and cover with the remaining layer of the sponge cake. Soak the top layer with syrup and spread the remaining mousse over the top.

Garnish the top with cocoa powder, a task made easier by the use of a fine sieve. To add a bit of a twist, soften the Ascanio mirror glaze and spread over the cocoa garnish, dragging some small grooves into it.
