Cooking Lessons Baking and Pastry Fundamentals 4 — Questions and Answers
Question 1: What distinguishes puff pastry from a standard pie dough?
- Puff pastry contains yeast for rising
- Puff pastry uses no fat at all
- Puff pastry must be deep-fried
- Puff pastry is laminated with butter through repeated folds to create hundreds of layers (Correct answer)
Correct answer: Puff pastry is laminated with butter through repeated folds to create hundreds of layers
Lamination folds a butter block into dough repeatedly, producing many thin layers that puff with steam.
Question 2: Why do choux pastry shells like éclairs puff up hollow without any leavening agent?
- High moisture in the dough turns to steam and inflates the shell (Correct answer)
- The eggs act as a chemical leavener
- The flour contains natural yeast
- The sugar caramelizes and expands
Correct answer: High moisture in the dough turns to steam and inflates the shell
Choux dough is very wet, and the steam generated in a hot oven inflates the pastry before the structure sets.
Question 3: A batch of cookies spreads into flat puddles. Which fix is most effective?
- Add more sugar to the dough
- Chill the dough before baking to firm the butter (Correct answer)
- Bake at a lower temperature for longer
- Use melted butter instead of softened
Correct answer: Chill the dough before baking to firm the butter
Chilled dough holds its shape longer in the oven because the butter melts more slowly.
Question 4: What does 'proofing' mean in yeast baking?
- Testing the oven temperature with a thermometer
- Kneading the dough until smooth
- Letting shaped dough rise a final time before baking (Correct answer)
- Scoring the top of the loaf
Correct answer: Letting shaped dough rise a final time before baking
Proofing is the final fermentation of shaped dough that builds volume before it goes in the oven.
Question 5: Which sign indicates that a custard like crème anglaise is properly cooked?
- It coats the back of a spoon and holds a line drawn through it (Correct answer)
- It boils vigorously for one minute
- It turns completely solid
- It separates into curds and whey
Correct answer: It coats the back of a spoon and holds a line drawn through it
Crème anglaise is done at the nappe stage, around 170-180°F, when it evenly coats a spoon; boiling would curdle it.
Question 6: Why is a water bath (bain-marie) used when baking cheesecake?
- It steams the crust to keep it soft
- It doubles the baking speed
- It adds moisture directly into the batter
- It provides gentle, even heat that prevents cracking and curdling (Correct answer)
Correct answer: It provides gentle, even heat that prevents cracking and curdling
The surrounding water moderates the oven heat so the delicate egg custard cooks evenly without cracking.
Question 7: What is the purpose of scoring the top of a bread loaf before baking?
- It lets excess salt escape
- It controls where the loaf expands during oven spring (Correct answer)
- It keeps the yeast from overworking
- It seals in moisture permanently
Correct answer: It controls where the loaf expands during oven spring
Score marks give the expanding dough a planned weak point so it opens attractively instead of bursting randomly.
