Start with the caramel :
Put the sugar in a pot at medium heat and stir until it becomes brown. Then take it off the heat.
Immediatly pour the caramel into a pie mold
Cut 3 to 4 apples in half, remove the seeds, then put them in the mold.
Then, cut chunks and use them to fill the gaps.
Finally, cut the rest into slices and fill the mold to the top.
Next, use the short pastry sheet to cover the mold. Fold the edges then seal it, but not to well, as the steam has to come out when it is in the oven.
Bake for 45 minutes at 180°C / 356°F
Et voilà !
Don't hesitate to add a scoop of vanilla ice cream with your slice, and enjoy !
