Preheat oven to 400°F/ 200°C.

Unfold the puff pastry sheet onto a parchment paper. On the long side, fold both sides towards the middle until they overlap each other at about 4 cm. Press a bit at the folds just to create a crease, then unfold to original shape. From the crease cut diagonal slits going out the side's edges about 1 inch apart and do the same on the other side. Cut and remove the top and bottom 2 leaves. Set aside for a while.

Combine sugar and cinnamon powder in a deep bowl. Add the apple slices, raisins and apricots and mix well until all are coated.

Beat the egg white until a bit frothy. Brush the puff pastry sheet with egg white. Sprinkle the middle part of the pastry with almond flakes evenly. Spread the apples over the almond flakes. Be sure not the go over the crease and leave an inch at the top and bottom uncovered. Fold the top over the apples, fold the leaves over the apples from one side and then the other to form the braid. Fold the bottom over the last leaves to finish.

Bake for 18-20 minutes or until golden brown.
