All-Purpose Flour (Best Option)
1 cup bread flour = 1 cup all-purpose flourAll-purpose flour has a protein content typically between 10-12%, lower than bread flour's 12-14%. This moderate protein level allows for sufficient gluten development to hold the dough together while preventing excessive toughness. In pie crusts, this balance is ideal for a tender yet durable texture.
When substituting, handle the dough gently to avoid overworking, which can toughen the crust. Slightly reduce mixing time and consider chilling the dough well before rolling to maintain flakiness.
The final crust will be marginally less chewy and slightly more tender compared to bread flour but will still have excellent flakiness and structural integrity.
