1. Blend the flour, almond flour, sugar and salt in a food processor.
  2. Add the butter and water until a dough is formed.
  3. Form the dough into a ball and refrigerate for one hour.
  4. While the dough is chilling, mix all of the filling ingredients together.
  5. Once the dough is cold, roll it out onto a floured surface and make a circle of about 15 inches wide.
  6. Move the dough onto a baking sheet lined with parchment paper.
  7. Place the apple filling in the middle of the circle of dough, leaving a 3-inch border of dough. Fold the dough around the filling to make a crust.
  8. Brush the top of the dough with an egg wash and sprinkle some sugar on top of the crust.
  9. Bake at 350F for 40 minutes, or until golden brown.
