Step 1

Preheat the oven to 425 degrees F. Line a baking sheet with parchment paper. In a bowl, stir together the sugar, cinnamon and salt.

Step 2

Place the puff pastry on the parchment paper. Whisk together the egg and water and brush it all over the puff pastry. Sprinkling a few tablespoons of the cinnamon sugar all over the puff pastry. Place the apples on top, in whatever decoration you would like. I used the cuts in the pastry as a guide to layer really thin apple slices. Sprinkle a little more of the cinnamon sugar over the apples.

Step 3

Bake the pastry for 25 minutes, or until golden and puffed. Remove it from the oven and cut into squares. Serve immediately. Serve with caramel sauce if you’d like!
