Flaky pastry filled with spiced apples, raisins, and cinnamon, baked until golden brown, powdered sugar for a classic, comforting dessert.
Place the sliced apples in a bowl, squeezed juice of a lemon, sugar and cinnamon and mix together.
Open the sheet of puff pastry and leave it on its paper.
Spread 4 tablespoons jam in the middle lengthwise.
Lay the sliced apples over the jam and top with a few walnuts and raisins.
Fold over one side of the pastry (which is nearest to you) over the apples.
Spread a little jam over the pastry and fold over the other side on top of it, till it covers the top, it doesn't need to go all the way down over the side. Seal and press the edges with a fork (for the top just brush down slightly with the fork).
In a small bowl mix the egg yolk and yoghurt together and generously brush the pastry all over.
Top with sliced apples next to each other and brush with remaining egg yolk mixture. Put a few dots of butter on top. Sprinkle the apples with sugar and scatter a few chopped walnuts and raisins.
Bake in oven 180C/350F for 25 minutes or until pastry is golden.
Serve warm with vanilla ice-cream or whipped cream.
