ACF Baking and Pastry Fundamentals 2 — Questions and Answers
Question 1: What is the primary function of eggs in a chiffon cake batter?
- Add color only
- Provide structure, leavening, and emulsification (Correct answer)
- Prevent gluten formation
- Reduce sweetness
Correct answer: Provide structure, leavening, and emulsification
Eggs contribute structure through protein coagulation, leavening via whipped air, and emulsification from yolk lecithin in chiffon cakes.
Question 2: Which type of flour produces the most tender pie crust?
- Bread flour
- All-purpose flour
- Pastry flour (Correct answer)
- Semolina flour
Correct answer: Pastry flour
Pastry flour has a lower protein content (8–9%) than all-purpose, resulting in less gluten development and a more tender crust.
Question 3: What technique is used to create flaky layers in croissants?
- Creaming
- Lamination (Correct answer)
- Tempering
- Scalding
Correct answer: Lamination
Lamination involves repeatedly folding butter into dough to create hundreds of distinct alternating layers that puff during baking.
Question 4: At what internal temperature is a properly baked custard considered set?
- 160°F (71°C)
- 180°F (82°C)
- 170°F (77°C) (Correct answer)
- 155°F (68°C)
Correct answer: 170°F (77°C)
Baked custards are considered fully set and safe when they reach an internal temperature of 170°F–175°F (77°C).
Question 5: Which fat produces the most flavorful and flaky croissant?
- Vegetable shortening
- Margarine
- Butter (Correct answer)
- Lard
Correct answer: Butter
Butter is preferred for croissants because its flavor, water content (which creates steam), and plasticity produce the best flakiness and taste.
Question 6: What is the purpose of 'docking' a pie shell before blind baking?
- Add flavor
- Prevent the dough from shrinking on the sides
- Allow steam to escape and prevent puffing (Correct answer)
- Create a decorative pattern
Correct answer: Allow steam to escape and prevent puffing
Docking (piercing with a fork or docker) allows steam to escape so the crust bakes flat without bubbling or puffing.
Question 7: Which mixing method is used for traditional pound cake?
- Biscuit method
- Creaming method (Correct answer)
- Muffin method
- Chiffon method
Correct answer: Creaming method
Pound cake uses the creaming method, where fat and sugar are beaten together to incorporate air before adding eggs and flour.
