CPM Pie Crust Preparation 3 — Questions and Answers
Question 1: What visual cue indicates that fat has been properly cut into flour for a flaky pie crust?
- The mixture looks like fine sand
- The mixture resembles pea-sized pieces with some coarser bits (Correct answer)
- The mixture is completely smooth and uniform
- The mixture turns slightly yellow
Correct answer: The mixture resembles pea-sized pieces with some coarser bits
Pea-sized fat pieces dispersed through flour create the steam pockets that produce flaky layers during baking.
Question 2: Why should pie dough rest in the refrigerator before rolling?
- To firm up the fat and allow gluten to relax (Correct answer)
- To allow the yeast to activate
- To increase the dough's sweetness
- To dry out excess moisture
Correct answer: To firm up the fat and allow gluten to relax
Resting firms the fat back up after handling and allows gluten strands to relax, preventing shrinkage during rolling and baking.
Question 3: When a recipe calls for 'rubbing' fat into flour by hand, what technique minimizes heat transfer?
- Using your palms to press the fat in firmly
- Using just your fingertips in a quick, light motion (Correct answer)
- Squeezing the mixture in your fists repeatedly
- Mixing with your whole hand submerged in the flour
Correct answer: Using just your fingertips in a quick, light motion
Using only fingertips minimizes contact area and time, keeping body heat from melting the fat.
Question 4: What problem does docking (pricking) a pie crust solve?
- Prevents the crust from shrinking on the sides
- Prevents steam bubbles from puffing the crust up during blind baking (Correct answer)
- Helps the egg wash adhere better
- Allows the filling to bond with the crust
Correct answer: Prevents steam bubbles from puffing the crust up during blind baking
Docking creates small holes that allow steam to escape, preventing the crust bottom from bubbling or lifting during baking.
Question 5: Which mixing method results in a mealy (crumbly, less flaky) pie crust texture?
- Cutting fat into flour until only pea-sized pieces remain
- Blending fat into flour until it resembles coarse cornmeal (Correct answer)
- Freezing the fat before use
- Adding ice water all at once
Correct answer: Blending fat into flour until it resembles coarse cornmeal
When fat is worked into flour more completely (coarse-meal stage), it coats flour particles and produces a crumbly, mealy texture ideal for bottom crusts holding wet fillings.
Question 6: What is the 'fraisage' technique in pie crust making?
- Rolling the dough out on a floured marble slab
- Smearing the dough across the work surface with the heel of the hand to distribute fat (Correct answer)
- Chilling the dough between two sheets of parchment
- Folding the dough multiple times like puff pastry
Correct answer: Smearing the dough across the work surface with the heel of the hand to distribute fat
Fraisage is a French technique of smearing dough with the heel of the hand to evenly distribute fat without overworking the gluten.
Question 7: If a pie crust shrinks significantly during baking, what is the most likely cause?
- Too much fat was used
- Insufficient resting time allowed gluten tension to remain in the dough (Correct answer)
- The oven temperature was too low
- Too much sugar was added to the dough
Correct answer: Insufficient resting time allowed gluten tension to remain in the dough
Overstretched, unrelaxed gluten springs back during baking; resting lets gluten relax so the crust holds its shape.
