CPM Flour, Fat & Liquid Selection 3

Question 1

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

Accepted Answer

The dough was not rested in the refrigerator before baking

Answer

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

Question 2

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

Accepted Answer

Inhibits gluten formation for a more tender crust

Answer

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

Question 3

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

Accepted Answer

Butter

Answer

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

Question 4

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

Accepted Answer

Add extra liquid to compensate for bran absorption

Answer

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

Question 5

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

Accepted Answer

Rich flavor and color

Answer

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