- 2 1/2 cups all-purpose flour
- Fine sea salt
- 1/4 teaspoon baking powder
- 1/2 pound (2 sticks) cold unsalted butter, cut into cubes, plus more for greasing
- About 1/3 cup ice-cold water
- Put the flour and baking powder in the bowl of a food processor and pulse to combine. Add the cold butter cubes and pulse a few times until the mixture begins to become mealy and the butter forms plainly visible pea-size nuggets
- Dissolve 1/2 teaspoon salt in the water. With the motor running, pour in the water and let mix, just until the dough pulls together. Do not over-mix the dough. If it appears dry and is not holding together, add a few additional tablespoons of water.
- Form the dough into a ball, flatten, and wrap in plastic wrap, and refrigerate until ready to use.
- Lightly flour a pastry board and a rolling pin and unwrap the dough. Divide the dough into 2 equal pieces and keep the second piece refrigerated. Tamp down the dough with the rolling pin and gently begin to roll it out into a circular pie shape by rolling evenly in one-eighth turns to keep the rolling even. When the dough is rolled out to an even thickness of about 1/8-inch and is about 12 inches in diameter, it is ready to be transferred to a 10-inch pie dish.
- Lightly butter the dish, lift the dough with the rolling pin by partially rolling the dough up on the pin, center the dough in the dish, and unroll. Pierce the dough in several places with the tines of a fork.
- Roll the second half of the dough into a circle slightly larger than the pie dish. Fill the bottom crust with your chosen filling. Cover the filling with the top half of the dough. Using both hands, crimp the edges of the 2 crusts together to seal. With a sharp knife, make several crosshatch slits in the top crust. Brush with the egg wash and bake in a preheated 375 degree F oven for 35 to 40 minutes. Remove from the oven and cool for 20 minutes.
