Critical Success Points

  • Baking the sponge at 160°C
  • Assembly and emulsification of the buttercream (butter and custard temperatures)
  • Firm whipping of the French meringue
  • Low‑temperature baking of the meringue fingers
  • Warm white chocolate glaze to avoid melting the meringue

Safety Warnings

  • Be careful of burns when handling melted butter and hot chocolate.
  • Use the thermometer to avoid overheating the custard (prevent curdled eggs).
  • Do not open the oven door during the meringue baking, otherwise it may collapse.
