  • Divide the cocoa sponge cake batter between 4 Silpat-lined baking sheets (400 g each) within 35.5 x 55 cm frames. Remove the frames and bake in a 220°C convection oven for approximately 6 minutes. Remove from the oven and transfer immediately to cooling racks to let cool. Refrigerate overnight.
  • Lightly whip the chocolate cremeux with the whisk attachment. Form tubes with rhodoid sheets (Ø3 cm x 55 cm long). Pipe the cremeux into each tube then place the tubes in the freezer.
  • Whisk the compote until smooth then spread 600 g onto each sheet of sponge cake (crust side) and let set in the refrigerator.
  • Spread with 400 g of vanilla diplomat cream. Place the tube of chocolate cremeux, pressing it down lightly into the diplomat cream then roll up the log cake. Place in the freezer.
  • Whisk the remaining vanilla diplomate cream and spread 400 g on a 54 x 24 cm rhodoid sheet. Place the frozen roll on the edge and roll up. Return to the freezer.
  • Spray with a thin coating of cherry red glaze. Whip the Sculpture with the sugar and pipe out onto the logs in a staggered row using a 15 mm fine star tip.
  • Then pipe out more Sculpture on the ends of the log and tap with a palette knife to create a textured surface. Decorate with chocolate trees, sprinkle with decorative icing sugar then decorate with a few drained sour cherries preserved in alcohol.
