This recipe outlines the creation of a versatile and perfectly flaky pie crust. Utilizing cold butter and shortening, along with ice water, egg yolk, and vinegar, it guides through combining ingredients to achieve optimal tenderness and structure. The dough is then chilled, ready for various sweet or savory pie fillings.
The key to a truly flaky pie crust lies in maintaining cold ingredients and avoiding overworking the dough. Use well-chilled butter and shortening; the shortening contributes to flakiness, while butter adds rich flavor. When cutting in the fats, aim for pea-sized pieces to create steam pockets during baking, resulting in a tender, flaky texture. Incorporate the liquid just until the dough comes together; too much mixing develops gluten, leading to a tough crust. The egg yolk enriches the dough, and a touch of vinegar helps tenderize the gluten, making the crust more pliable and less prone to shrinking. Chilling the dough thoroughly (at least 2 hours) allows the gluten to relax and the fats to firm up, making it easier to roll and ensuring a superior texture.
