Serving: This dessert is best served warm, ideally straight from the oven. A scoop of vanilla ice cream or a dollop of whipped cream will take it to the next level.
Storage: If you have leftovers (though unlikely!), store them in an airtight container in the fridge for up to 2 days. Reheat in the oven at 350°F (175°C) for about 5 minutes to bring back the flaky texture.

Freezing: If you plan to freeze this dessert, you can freeze the baked pastry after cooling completely. To reheat, place it in the oven until it’s crisp again.
Variations:

Spiced Up: Add a pinch of ground ginger or cardamom to the caramel sauce for an added spice kick.
Add fruits: Feel free to throw in some berries or pears along with the apples to create a mixed fruit version.
Gluten-Free: Swap the puff pastry for a gluten-free version, or make a crustless version by simply layering the caramelized apples in a baking dish.
Vegan: Use a dairy-free butter alternative and replace the puff pastry with a vegan-friendly version.
