Preheat your oven to 180°C (350°F, Gas Mark 4).
Line a baking tray with baking parchment to prevent the pies from sticking and then place the pastry rectangle bases on the tray
Spoon the apple mixture onto each pastry base. If you like, gently roll up the edges of each base to create a small border, which will make adding the pastry strips easier.
Lay the pastry strips across each apple-filled base in a crisscross pattern, like mummy bandages, leaving a small space open for the eyes. To help the strips stick, use a dab of water where the strips meet the edges.
Pop the baking tray into the oven for 25 to 30 minutes. The pastry should become golden brown and rise.
Remove the tray from the oven and leave to cool. When they are cool pop on the candy eyes to create the mummy effect.
