Chill the Crisco (Crucial for Flakes!): Before you even think about mixing, measure out your Crisco and pop it in the freezer for at least one hour. Truly cold fat is the secret weapon.
Combine Dry Ingredients: In a large bowl, whisk together the 2 cups of all-purpose flour and ¾ teaspoon of salt.
Cut in the Cold Crisco: Add your properly chilled Crisco to the flour mixture. Using a pastry blender, two knives, or a large fork, cut the shortening into the flour until the mixture looks like coarse crumbs with some pea-sized pieces of Crisco still visible. Work quickly.
Introduce Ice Water (Slowly Does It): Start adding the ice water, one tablespoon at a time. Begin with 3 tablespoons, then gently toss the mixture with a fork or spatula after each addition.
Test for Hydration: After adding about 4-5 tablespoons, squeeze a small amount of the mixture. If it holds together, stop adding water. If still very crumbly, add 1 more tablespoon at a time, testing after each, until it just holds together. Do not add too much water.
Form the Dough (Handle Gently!): Use your hands to quickly and gently gather the mixture into a ball. Do not knead. Minimal handling is key.
Divide and Chill (Mandatory Rest): Divide the dough ball in half. Gently flatten each half into a 1-inch thick disk. Wrap each disk tightly in plastic wrap. Refrigerate for at least 30 minutes.
Roll It Out: On a lightly floured surface with a lightly floured rolling pin, roll one disk of dough from the center outwards into a 12-inch circle (about ⅛-inch thick), rotating occasionally.
Transfer to the Pie Plate: Carefully roll the dough loosely around your rolling pin and unroll it gently over a 9-inch pie plate. Ease the dough into the plate without stretching.
Trim and Crimp: Trim excess dough leaving a ½-inch overhang. Fold this overhang under itself and crimp or flute the edge as desired.
For Blind Baking (Unbaked Fillings): Preheat oven to 425°F (220°C). Prick the bottom and sides of the crust with a fork. Optional: Line with parchment/foil and fill with pie weights/beans. Bake for 12-15 minutes until lightly golden. (If using weights, remove after 10-12 min and finish baking). Cool completely before filling.
For Baked Fillings: Fill the unbaked crust as per your pie recipe. Add top crust if needed, cut vents, and bake according to recipe directions.
