French Custard Pie - With Apples (flan Parisien)

"French Custard pie with Apples bakes up to a smooth and creamy texture of custard with the delicious sweetness of fresh apples. It's absolutely loved for its simplicity, basic ingredients and great flavors. It's the perfect dessert, with rustic charm. Plus it not overly sweet creating a balance that allows the flavors of the custard and apples to shine. Flan Parisien is a French custard pie also known as Flan pâtissier. Its is quite popular in France, in fact you will find them in most patisserie shops. Typically, the French Apple Custard pie is baked with a puff pastry base. However, my version takes a twist by being a crustless pie with fresh sliced apples. "
