Crush the egg, add a pinch of salt, add a tablespoon of sugar, a tablespoon of cinnamon and mix the composition well until it becomes creamy, add the butter and incorporate everything. Then put a tablespoon of water and flour and knead the composition well and then put it in the fridge until you prepare the filling.
If it is more convenient for you, put all the dough ingredients in the food processor and mix them, then leave the composition to cool in the fridge. For the filling, wash and clean the apples, grate them or cut them into cubes. squeeze the juice they leave, add the sugar and a tablespoon of cinnamon. Squeeze more apples, if necessary or you can add a tablespoon of semolina to the composition to absorb the juice that apples leave.
Another option would be to heat the apples in the pan until the juice evaporates from the composition, in which case you let them cool before putting them over the dough. Preheat the oven to 200 degrees. Cut the dough out of the fridge into two equal parts.
Spread a part and put it in the tray after you have greased with butter / butter or placed a baking sheet in the tray. Place the filling over it, and place on top, like a lace / grid, strips of dough stretched and cut. Bake the tart for 30 minutes, and after removing it from the oven, let it cool for a few minutes, then cut it into pieces to be served. Good appetite!
