• Gather all the ingredients.
• Preheat the oven to 195°C.

Prepare the filling

• In a mixing bowl add lemon zest and the juice.
• Wash the apples, peel them, cut out the core and slice into wedges, and then into bite-size pieces.

  Add the apples into the mixing bowl.

  Mix well so that all the apples are nicely coated with lemon. (Note 1).
• Add sugars, cinnamon, vanilla paste, butter, and cornstarch to the mixing bowl. Mix well to incorporate all the ingredients.

  Cover with a clean cloth and set aside.

Prepare the pie crust

• Measure out the flour, salt, and powdered sugar. Add all to a mixing bowl.

  Place in the freezer for 15 minutes.
• Measure the butter and cut into 3cm rectangles.

  Place in the freezer for 15 minutes.
• Add ice cubes and water in a bowl. Place in the fridge.
• After all the ingredients are chilled mix the dry ingredients in the food processor by pulsing a couple of times. (Note 2)
• Add all the butter and pulse several times or until the butter is coarsely broken into the flour.
• Add 55g of ice water and mix the dough. If it is still dry and does not come together if squeezed add a bit more water. (Note 3)

  There should be some dry pieces of dough on the bottom of the food processor bowl.
• Once the majority of the dough does come together take the dough out and onto a clean work surface.

  Gently gather the dough and the dry pieces and knead just enough for the dough not to have and dry pieces.

  Roll the dough into a cylinder and cut in half.

  Make a disc out of the two halves and place in a zip lock bag.

  Let the dough rest in the fridge for at least 1 hour. (Note 4)

Assemble the pie

• Take out one piece of pie dough from the fridge and place it on the working surface.

  Dust it lightly with flour.

  Roll out the dough, always from the middle outwards, until it is around 3mm thick. (Note 5)
• Place the rolled out pie crust on the pie dish.

  Gently tap the dough to even the bottom out, especially around the edges. There should not be any gaps on the bottom part of the dough. Set aside.
• Similarly, roll the top part of the dough.
• If you are doing the lacing then cut 10 wider (1cm) ribbons, and 5 thin ones (3mm).

  Assemble 5 ribbons by placing the thinner one on top of the thicker one. Set aside.
• Add pie filling to the pie dish.

  Level the filling, but be careful not to push into the pie dough.
• Arrange the ribbons as described in the post.
• Make the egg wash by mixing the egg yolk and the heavy cream.

  Brush the pie with the egg wash and sprinkle with sugar.
• Bake the pie for 30 minutes on 196°C and then the remaining 20 minutes on 185°C.
• Let the pie cool to room temperature before serving.
