Here's the recipe for my From-Scratch Apple Pie in process. Step 1:
Sift together 2 cups flour and 1 teaspoon salt.
Cut 1 stick of cold butter (1/2 cup) into 1/4" cubes and add to the flour.
Using a fork, cut in the cubed butter. Squish the butter between the fork's tines and mash the butter pieces into the flour until you achieve the texture of cornmeal.
Take another 1/2 stick of cold butter (1/4 cup) and cut it into 1/4" cubes. Add to the flour mixture and stir to evenly distribute the butter cubes.
Take 1 egg yolk and add enough cold water to equal 1/2 cup. Scramble.
Add the yolk-water mixture to the flour. Stir lightly until you form a loose dough ball. If the dough is very dry, add more water--1 tablespoon at a time--until the dough is silky.
Use your hand to form a cohesive dough ball. Wrap the dough in plastic wrap and refrigerate for at least 30 minutes before rolling out.
Next step: The Filling.
