Preheat oven to 200°C. Slice apples into round, even cylinders. If you have a corer, remove the center. If not, carefully cut out a small circle using a knife.

In one bowl, mix sugar and cinnamon. In another, mix egg yolk and a pinch of cinnamon. Dip apple slices in the cinnamon sugar mix.

Wrap puff pastry strips around each apple slice in a criss-cross or “pumpkin” shape.

Brush with the egg yolk mix, sprinkle with extra sugar. Bake for 15–20 minutes until golden and crispy.
