Which statement about pastry flour is true?

• A. It is the strongest flour
• B. It is the best flour for pie pastry
• C. It is identical to all-purpose flour
• D. It has the highest protein content

Answer: (B)

Pastry flour is chosen for its lower protein content, which means less gluten forms when you mix and roll dough. The goal in pie pastry is tenderness and a flaky, crumbly texture, and that tenderness comes from limiting gluten development while still providing enough structure to hold together in the oven. Because pastry flour sits between cake and all-purpose in protein content, it gives a workable dough that stays tender but still rolls out smoothly, making it well suited for pie crusts. It isn’t the strongest flour—that would be bread flour—and it isn’t identical to all-purpose flour, which has a higher protein level and behaves differently in doughs. It also does not have the highest protein content. So the statement that pastry flour is the best flour for pie pastry is true. If you don’t have pastry flour, you can approximate it by blending all-purpose flour with a touch of cake flour to lower the overall protein content.
