All-Purpose Flour with Cornstarch (Best Option)
For every 1 cup cake flour, use 1 cup all-purpose flour minus 2 tablespoons, plus 2 tablespoons cornstarchCake flour has a lower protein content (about 7-8%) compared to all-purpose flour (10-12%). Cornstarch dilutes the protein in all-purpose flour, reducing gluten formation and mimicking cake flour's softness. This balance is crucial for pie crusts that require tenderness without losing structural integrity.
To ensure success, sift the all-purpose flour and cornstarch together before measuring to achieve even distribution. Avoid overworking the dough to prevent gluten development, which can toughen the crust.
The final crust will be flaky and tender, closely resembling one made with cake flour, with a delicate crumb and good handling properties.
