Flour, sugar, and salt are combined together
Add 10 Tbsp. butter cubes and chop with a pastry blender until pea-sized clumps remain (some larger are fine)
Drizzle 1 Tbsp. at a time, stir until the mixture clumps. Knead the dough until mixed
Form a disc (about 5 to 6 inches across). Chill for 30-60 minutes in plastic wrap
Heat up to 375 degrees on parchment on an 18-by-13-inch rimmed baking sheet
Remove dough from the fridge, flour top, and roll into a 13.5-inch round
Stretch the dough on a parchment-lined baking sheet (it will run up the sides). Refrigerate
Peel, core, half, and thinly slice the apples (1/6-inch thickness, 1/4-inch for golden delicious). Mix apples with sugar and cinnamon in a large mixing bowl
Arrange apples in a circle on the crust, leaving a 2-inch margin bare
Cover apples with dough. Start at one point in the round and fold every 3 inches
Whisk egg and water in a bowl, then brush pie crust edges. Sugar the edges. Dot apples with remaining butter
Bake until soft, 40 to 50 minutes. After 10 minutes, cool. Servable with honey or apricot preserves. Vanilla ice cream is optional
Modifications: It's excellent as-is, but try these creative variations
Nuts: Near the conclusion of baking, sprinkle with nuts
Caramel sauce replaces honey or jam
Vanilla glaze: Vanilla glaze replaces the topper. Combine 1/3 cup icing sugar, 2 drops of milk, and 1/4 drop of vanilla
Add additional spices like nutmeg, allspice, cardamom, and ginger. Double the cinnamon if required
Substitute one of the apples with a hard, ripe pear and add two teaspoons of cornstarch to the filling because there will be additional moisture
Cranberries: Before baking, sprinkle with 1 cup of fresh cranberries. Boost the amount of sugar in a recipe by two teaspoons
