Start by shaping the bar in a silicone mould.
Fill the mould to two-thirds with the vanilla mousse.
Using a small palette knife, pull up the mousse along the edges.
Scoop the apples into the centre of the mould, then top with a layer of sponge cake.
Smooth off any excess mousse to get a flat bottom.
Freeze.
Freeze.
Remove the bar from the mould and pipe on a mixture of gold chocolate and cocoa butter (50/50).
Next, pipe a few dots of the baked milk gel on top.
Strain the marinated apple strings and arrange them on top of the cream.
Mix the sieved apple marinade with xanthan gum so that you can blend it up to a foam.
Pipe another dot of the baked milk gel next to the bar and spoon a quenelle of the ice cream on top of the cream.
Garnish with a puff pastry crisp and Atsina cress.
Finish with a spoonful of foam.
