Critical Success Points

  • Keep the butter very cold when preparing the dough.
  • Do not overwork the dough to retain flakiness.
  • Gently caramelize the onions for 20 minutes.
  • Do not add too much water to the dough to avoid a sticky texture.
  • Bake at 180°C until the crust is nicely golden.

Safety Warnings

  • Handle cold butter with clean hands to avoid contamination.
  • Be careful of hot oil splatters when cooking the onions.
  • Use gloves or a kitchen sleeve to remove the hot dish from the oven.
