1-First Step: Mise en Place Measure all ingredients precisely. Cube the cold butter into 1/2-inch pieces and freeze for 15 minutes. Fill a glass with ice and water; chill the bowl and pastry cutter in the fridge. This setup prevents warming, crucial for how to make flaky pie crust.

2-Second Step: Mix Dry Ingredients In the chilled bowl, whisk flour, salt, and sugar. Work quickly to keep cool. This even distribution ensures consistent texture in your homemade pie crust from scratch.

3-Third Step: Cut in the Butter Add frozen butter cubes. Use a pastry blender or fork to cut until pea-sized crumbs form, with some larger chunks. Avoid overmixing; visible butter bits create steam pockets for flakiness in this perfect flaky pie dough recipe. Takes 3-5 minutes.

4-Fourth Step: Add Liquids Drizzle vinegar over mixture if using. Sprinkle 1/3 cup ice water, one tablespoon at a time. Toss with a fork until dough starts to clump. Add more water if dry, but stop when it holds together when squeezed. Over-wetting toughens the crust.

5-Fifth Step: Form the Dough Divide into two discs, about 6 inches wide. Wrap each tightly in plastic wrap. Flatten slightly for even chilling. Refrigerate 1 hour or up to 2 days. Chilling relaxes gluten and firms butter.

6-Sixth Step: Roll Out the Dough On a floured surface, roll one disc from center outward to 12-inch circle, 1/8-inch thick. Rotate often to prevent sticking. Fold gently in half, transfer to pie plate, unfold. Trim overhang to 1/2 inch.

7-Seventh Step: Assemble and Final Touches Add filling, top with second crust. Crimp edges. Cut vents. Chill 30 minutes before baking at 425°F for 15 minutes, then 375°F until golden. For blind bake, line with foil and weights, bake 20 minutes, remove foil, bake 10 more.
