Make the dough

• In a large bowl, mix the flour, sugar and salt.
• Add the diced cold butter and work it in with your fingers or a pastry cutter until crumbly.
• Gradually add the cold water and knead until a dough forms.

Rest the dough

• Wrap the dough in plastic wrap and let it rest in the refrigerator.

Prepare the filling

• In a bowl, combine the apple slices with the sugar, flour, cinnamon and lemon juice.
• Mix well so everything is evenly coated.

Line the baking dish

• Roll out the dough on a floured surface until large enough to cover the baking dish and hang over the edges.
• Line the baking dish with the dough and trim the excess.
• Prick holes in the base with a fork.

Fill and cover

• Place the apple mixture into the lined dough.
• Roll out the remaining dough and use it as a cover, for example in a lattice pattern.
• Seal the edges well.

Bake

• Preheat the oven to 200 °C.
• Brush the top with the egg yolk mixed with the milk.
• Bake until the surface is golden brown and crispy.

Cool and serve

• Take the pie out of the oven and let it cool before cutting into pieces.
• Serve with a scoop of vanilla ice cream or fresh whipped cream.
