Preheat the oven to 200°C. Line a baking sheet with parchment paper.
02 -
Peel, core, and cut apples into pieces approximately 1 cm wide by 2.5–5 cm long. In a bowl, toss apple pieces with brown sugar, cornstarch, cinnamon, and salt until evenly coated.
03 -
In a medium saucepan, melt butter over medium heat. Add the apple mixture and cook, stirring frequently, for about 5 minutes until apples are just tender and the mixture thickens. Remove from heat and let cool slightly.
04 -
Unfold the defrosted puff pastry sheet. Cut it twice through the centre, horizontally and vertically, to create 4 equal squares. Divide the apple filling evenly among the centres of the pastry squares.
05 -
Beat the egg with water to create an egg wash. Brush the pastry edges with egg wash. Fold the pastry over the filling to form triangles, aligning the edges. Press the three open edges gently with a fork to seal, ensuring the filling remains enclosed.
06 -
Place the pies onto the prepared baking sheet. Brush the tops and sides of each with remaining egg wash.
07 -
Bake for 18–20 minutes, or until the pastry is puffed and golden brown. Remove from oven and transfer hand pies to a wire rack to cool.
08 -
In a small bowl, whisk together powdered sugar and heavy cream (or water) until a smooth, pourable glaze forms.
09 -
Once pastry is completely cool, drizzle the glaze over the tops. Allow glaze to set before serving.
