Cut the butter into even-sized pieces first and keep it in the fridge or freezer so it stays cold.
Add the flour, sugar, salt, and egg yolks to a food processor and pulse until evenly combined. Add the butter and pulse until the flour is evenly coated with pieces of butter.
Add the ice water gradually just until a dough forms. I need 4 and ½ tablespoons. Start with 3 and add more, a little at a time, just until a dough forms.
Divide the dough in half and shape each into a round, flat disc. Wrap with plastic wrap and let rest and chill in the fridge for at least 1 hour and up to 3 days.
Lightly dust a clean surface and a rolling pin with flour. Remove one portion of dough from the fridge and roll it out into a 12" circle. Lightly sprinkle the dough, surface, and rolling pin every so often so it doesn't stick. Place the dough into a 9" pie dish. Trim the edges, leaving a 1" overhang around the sides.
If the recipe doesn't call for blind-baking the pie crust, brush the inside of the dough with a lightly beaten egg before adding the filling. Cover with the second portion of dough if the recipe calls for it and brush the top with a lightly beaten egg. Keep the pie in the freezer while the oven preheats.
