Use firm baking apples like Granny Smith or Braeburn for the best texture and flavor.
Be cautious when working with hot sugar; it burns easily and can be dangerous.
If you prefer not to use baking parchment, ensure your pan is well-buttered, but unmolding may be more difficult.
For extra flavor, add a cinnamon stick or a splash of Calvados to the caramel before adding the apples.
Best served warm. Leftovers can be stored covered at room temperature for up to 2 days, but the pastry may soften.
