Method

Honey sponge

The calculation is for an 18cm (7.09 inch) baking tin.

  • Whip the egg whites with half the sugar and salt until peaks.⠀
  • Whip the yolks with the remaining sugar until white and fluffy. Pour in the oil, honey, and whip.
  • Sift flour and baking powder. Add to the yolk mass alternately 1/3 flour and whites, each time carefully and gently mixing with a spatula from top to bottom.
  • Bake at 338F (170C) for 40-50 minutes, check the readiness with a dry skewer.
  • Cool the sponge, remove from the ring, wrap in cling film and refrigerate for several hours. Then cut into 3 cake layers.

Crispy pistachio layer

  • Mix everything and smooth on baking paper with a layer of 5mm (0.20 inch).
  • Freeze and chop.

Pistachio caramel

  • Mix the cream, sugar and butter in a saucepan, put on the heat. Add glucose syrup, and stir. Cook, stirring until slightly thickened and bubbles appear on the surface.⠀
  • Remove from the heat, add pistachio paste, and stir.
  • Leave at room temperature.

Sundae mousse

  • Soak the gelatin in water (1:6).
  • Bring the cream #1 to a boil, add chocolate, and leave for a minute. Stir until combined. Add the gelatin, and mix thoroughly.
  • Whip the cream #2 to soft peaks.
  • Combine both mixtures.

Coating cream

  • Mix very soft butter at room temperature with powdered sugar, and beat until white and fluffy.
  • Add the cream cheese, and beat.
  • Add pistachio paste, and mix thoroughly.

Cake assembly

  • Assemble the cake in a ring, lined with acetate film: sponge layer, crispies, mousse, freeze-dried raspberries, sponge layer, caramel, mousse, raspberries, sponge layer.
  • Cool the cake well (better overnight).
  • Cover it with coating cream. Decorate to your taste.
