Step 1: Prepare the Dough

1. In a large bowl, sift together the flour, sugar, and salt. Add the chilled butter cubes.
2. Using your hands or a pastry cutter, work the butter into the flour until the mixture resembles coarse crumbs.
3. Gradually add cold water, one tablespoon at a time, mixing until the dough comes together.
4. Divide the dough into two portions: one slightly larger for the base and a smaller one for the lattice top.
5. Shape each portion into a flat disc, wrap in cling film, and chill in the refrigerator for 40–60 minutes.

Step 2: Make the Filling

1. In a large bowl, combine the sliced apples and pomegranate seeds.
2. Add sugar, cinnamon, salt, flour, and lemon juice. Toss until evenly coated.

Step 3: Assemble the Pie

1. Preheat your oven to 200°C (400°F). Grease a pie dish lightly with butter.
2. Roll out the larger dough portion on a floured surface to fit your pie dish. Place it in the dish and trim excess edges.
3. Pour the prepared filling into the crust.
4. Roll out the smaller dough portion and cut into strips to create a lattice pattern on top of the filling.
5. Press down edges to seal and trim any excess dough. Decorate edges as desired.
6. Brush the lattice top with beaten egg yolk mixture.

Step 4: Bake

1. Place the pie in the preheated oven and bake for 40–45 minutes or until golden brown.
2. Allow to cool slightly before serving.
