Cooking Lessons Baking and Pastry Fundamentals 2 — Questions and Answers
Question 1: Why is butter kept cold when making flaky pie dough?
- Cold butter absorbs more flour
- Cold butter pieces create steam pockets that form flaky layers during baking (Correct answer)
- Cold butter prevents the dough from browning
- Cold butter makes the dough sweeter
Correct answer: Cold butter pieces create steam pockets that form flaky layers during baking
Solid butter pieces melt in the oven and release steam, separating the dough into flaky layers.
Question 2: What is the main role of gluten in bread dough?
- It adds sweetness to the crumb
- It prevents the crust from burning
- It keeps the yeast dormant
- It provides an elastic network that traps gas and gives structure (Correct answer)
Correct answer: It provides an elastic network that traps gas and gives structure
Gluten forms an elastic protein network that traps fermentation gases so the loaf can rise and hold its shape.
Question 3: A baker's cake turns out dense and gummy. Which mistake is the most likely cause?
- Overmixing the batter after adding flour (Correct answer)
- Using room-temperature eggs
- Preheating the oven
- Sifting the dry ingredients
Correct answer: Overmixing the batter after adding flour
Overmixing develops excess gluten, which makes cakes dense and gummy instead of tender.
Question 4: What temperature range of water is ideal for activating active dry yeast?
- 35-45°F
- 150-160°F
- 105-115°F (Correct answer)
- 200-212°F
Correct answer: 105-115°F
Water at 105-115°F wakes yeast efficiently; hotter water can kill it and colder water slows activation.
Question 5: Which ingredient pairing produces the leavening reaction when using baking soda?
- Baking soda plus salt
- Baking soda plus melted butter
- Baking soda plus egg whites
- Baking soda plus an acid like buttermilk or lemon juice (Correct answer)
Correct answer: Baking soda plus an acid like buttermilk or lemon juice
Baking soda is a base that needs an acidic ingredient to react and release carbon dioxide.
Question 6: What does 'docking' a pie or tart dough mean?
- Folding the dough into thirds
- Pricking the dough with a fork to prevent puffing during blind baking (Correct answer)
- Brushing the dough with egg wash
- Chilling the dough overnight
Correct answer: Pricking the dough with a fork to prevent puffing during blind baking
Docking pierces small holes that let steam escape so the crust bakes flat.
Question 7: Why do most recipes call for resting bread dough after kneading?
- To dry out the surface of the dough
- To lower the dough's temperature below freezing
- To let the gluten relax and the yeast produce gas for rising (Correct answer)
- To dissolve the salt completely
Correct answer: To let the gluten relax and the yeast produce gas for rising
Resting allows fermentation to leaven the dough while the gluten relaxes for easier shaping.
