The crust for an apple pie is basically the same than for a quiche but adding dates as sweetener, honey or syrups doesn’t allow the crust to be crusty. The recipe of the crust for making cheesecake can be used too for the apple pie.
Then, add the filling with apples and some tolerated sweetener, such as honey. I’ve added also some apple sauce with egg yolks to do a cream that coat the apples.
