Flour, Fat & Liquid Selection Flashcards

A baker notices their pie crust shrinks significantly during blind baking. What is the most likely cause?

Answer: The dough was not rested in the refrigerator before baking

Resting dough in the refrigerator relaxes gluten strands; skipping this step leaves tension in the dough that causes it to snap back and shrink.

What effect does adding a small amount of apple cider vinegar to pie dough have?

Answer: Inhibits gluten formation for a more tender crust

Acid in vinegar interferes with gluten bond formation, making the dough more tender and easier to work with.

Which fat has the highest water content among common pie crust options, which contributes to steam-leavening and flakiness?

Answer: Butter

Butter contains approximately 15–18% water, which converts to steam during baking and helps lift and separate pastry layers.

When substituting whole wheat flour for all-purpose flour in pie crust, what adjustment is typically needed?

Answer: Add extra liquid to compensate for bran absorption

The bran in whole wheat flour absorbs more liquid than refined flour, so additional water is needed to achieve proper dough consistency.

A pie crust made entirely with vegetable shortening will most likely lack which quality compared to one made with butter?

Answer: Rich flavor and color

Vegetable shortening produces a very tender, flaky crust but lacks the buttery flavor and golden color that dairy fat provides.

For a pie crust that needs to hold a very wet custard filling without becoming soggy, which technique best addresses this?

Answer: Blind baking the crust before adding the filling

Blind baking pre-cooks and sets the crust, creating a moisture barrier that prevents the wet filling from soaking through.

What is the role of salt in pie crust dough beyond seasoning?

Answer: It strengthens gluten structure and enhances flavor

Salt tightens gluten bonds, giving the crust enough structure to hold its shape, while also enhancing the overall flavor profile.
