CPM Flour, Fat & Liquid Selection 2 — Questions and Answers
Question 1: Which type of flour produces the most tender, flaky pie crust due to its low protein content?
- Bread flour
- All-purpose flour
- Pastry flour (Correct answer)
- Whole wheat flour
Correct answer: Pastry flour
Pastry flour has a protein content of 8–9%, which limits gluten development and results in a tender, flaky crust.
Question 2: When making pie crust, why is ice-cold water preferred over room-temperature water?
- It adds flavor to the dough
- It keeps fat cold to prevent gluten overdevelopment (Correct answer)
- It dissolves salt and sugar faster
- It increases dough elasticity
Correct answer: It keeps fat cold to prevent gluten overdevelopment
Cold water keeps fat pieces solid during mixing, which creates steam during baking and produces a flaky layered crust.
Question 3: A pie maker wants an exceptionally flaky crust with distinct layers. Which fat should they choose?
- Butter
- Vegetable shortening
- Lard (Correct answer)
- Coconut oil
Correct answer: Lard
Lard has a high plasticity range and large fat crystals that create distinct, well-separated flaky layers in pie crust.
Question 4: Which liquid addition to pie dough helps reduce gluten development while also adding richness?
- Cold water
- Milk
- Vinegar
- Vodka (Correct answer)
Correct answer: Vodka
Vodka contains ethanol, which does not promote gluten formation, allowing more liquid to be added for easier rolling without toughening the dough.
Question 5: What is the primary function of fat in pie crust dough?
- To add sweetness
- To coat flour proteins and inhibit gluten development (Correct answer)
- To leaven the dough
- To add color during baking
Correct answer: To coat flour proteins and inhibit gluten development
Fat coats flour proteins, preventing them from hydrating and bonding into gluten strands, which keeps the crust tender.
Question 6: A pie crust recipe calls for 'cutting in' the fat. What does this technique achieve?
- Fully melts the fat into the flour
- Creates small fat pieces coated with flour throughout the dough (Correct answer)
- Incorporates air to leaven the crust
- Removes excess fat from the mixture
Correct answer: Creates small fat pieces coated with flour throughout the dough
Cutting in distributes fat into small, flour-coated pieces that will melt during baking to create flaky, tender layers.
Question 7: Which flour protein content range is considered ideal for a classic American flaky pie crust?
- 12–14%
- 10–12%
- 8–10% (Correct answer)
- 6–8%
Correct answer: 8–10%
A protein content of 8–10% (typical of pastry or low-protein all-purpose flour) provides enough structure without creating excessive toughness.
