Make a dough of the flour, butter, 1 egg, sugar and pinch of salt. Make sure that you use cubes of cold butter when you start making the dough.
Once nicely mixed, let the dough rest for 1 hour in the refrigerator.
Soak the raisins in some hot water for about 20 minutes.
Butter the cake pan to make it non-stickable.
In the meanwhile, peel the apples, take out the core of the apples, and cut into 1 cm pieces. Add lemon zest, juice of half a lemon, sugar, cinnamon, vanilla and custard powder.
Add the raisins to the apple mixture.
Preheat the oven on 160 degrees Celsius or 320 degrees Fahrenheit.
When dough is ready, separate ⅓ of the dough. This will be used for the top of the apple pie. Roll the dough out to a thickness of ½ a centimeter.
Place the dough in the cake pan, and cover the bottom with breadcrumbs. Then add the apple mix.
Roll out ⅓ of the dough and make strips of the dough. Use these strips to weave a lattice pie crust.
Whisk 1 egg and brush the top of the pie.
Bake the pie for 45-55 minutes, and let it cool down completely before cutting the pie. Enjoy! Best with some whipped cream!
