How to cook
Pour out the mixture in a suitable buttered tray. Put it to bake in a preheated 390°F (200 °C) oven. Once the pie starts to rise, reduce the heat. Cut an apple into thin slices (if needed, use more fruit).
Shortly before the apple pie is fully baked, take it out and quickly arrange the slices of apples on top, then pour on sugar water and return to bake until finished.
