Sift flour grind into a bowl. Add brown sugar, cinnamon, and salt. Add softened butter and mix with a fork until everything is evenly mixed. It will look like crumbs.
1 Tbsp brown sugar, ½ tsp salt, ⅔ cup butter,, 1 pinch cinnamon, 2½ cups flour
Add the egg yolk and water. The dough should be elastic. Form a ball, wrap in cling foil and refrigerate for 30 minutes.
1 large yolk, 2-3 Tbsp water
Preheat the oven to 350F.
Wash your apples, remove the core, and slice.
Melt butter in a large pan over medium heat. Add sugar and wait until the sugar has completely dissolved. Add sliced apples, cinnamon and stir the apples a little with a wooden spatula. Cook for 3-5 minutes, stirring occasionally. They should release a little juice, but remain firm inside.
Take the dough out of the fridge and roll it out between two sheets of waxed parchment paper. Roll out until it becomes the size of a baking dish plus the sides. I used a 10 inch dish.
Place the rolled dough in a baking dish. Gently press dough down into the dish so that it lines the bottom and sides of the dish. Trim the edge with a knife or kitchen scissors.
Place caramelized apples into the crust. Optionally you can arrange fresh apple slices over the filling, sprinkling them with brown sugar and some cinnamon.
1 Tbsp brown sugar, 1 pinch cinnamon
Bake for 45 min. Let cool completely before serving.
Notes
For apple variety, Jonagold or honeycrisp apples are the best choice. They both hold well in the oven and have the sweetness you want in an apple tart, and other baked goods.
