Bring the crust and filling together.
- Roll out one dough disc and line a 9-inch pie dish.
- Pile in the apple filling, mounding it slightly in the center.
- Roll the second disc on top (or cut strips for a lattice) and seal the edges.
- Brush with beaten egg and cut a few slits to vent steam.
Tip: Sprinkle coarse sugar on top for a sparkly, crunchy finish.
