Ingredients: - 
For The Crust: - 
3 cups flour, 
¾ tsp salt,
2 Tbsp granulated sugar,
1 cup butter, cold & cubed,
8 Tbsp ice water.
For The Filling: - 
7 medium tart apples, peeled and sliced, 
2 Tbsp lemon juice,
¼ cup granulated sugar,
¼ cup brown sugar, packed,
2 Tbsp all-purpose flour, 
1 tsp cinnamon,
¼ tsp nutmeg,
1/8 tsp salt,
2 Tbsp butter

1 large egg, beaten,
1 Tbsp granulated sugar -
METHOD: - 
The Crust: - 
Place the flour, sugar, and salt in a food processor. Close lid and pulse a few times. With the processor on, gradually add the cubed butter. Then add the ice water. As soon as a ball forms, turn off the machine or if no food processor you can cut the butter into the flour mixture in a bowl with a pastry blender or a fork. Then stir in the water until completely combined. Knead with hands to form the dough.
Roll out half of the dough on a lightly floured surface to create a 12-inch disk, about ⅛" thick. Gently place in pie plate. -
The Filling: -
Preheat oven to 220°C. Place sliced apples in a large bowl. Sprinkle with lemon juice and toss together.
In another bowl, stir together remaining filling ingredients (except butter). Pour over apples and stir to combine. Pour filling into prepared crust. Dot with 2 Tbsp butter - 
Lattice Crust: - 
Roll out remaining dough as directed above. Use a pizza cutter to cut dough into 8 strips. Create a lattice pattern on top of pie.  Fold the edges under then use your fingers to crimp edges or you can use a fork to press around the edges if that's easier. Brush with egg and sprinkle with sugar.
Place pie in a preheated 220°C oven for 10 mins. Turn oven down to 175°C and continue baking for 40 mins. 
Let cool slightly and serve with ice cream.
