Cooking Lessons Baking and Pastry Fundamentals 5 — Questions and Answers
Question 1: Which stage of whipped egg whites is correct for folding into a soufflé base?
- Foamy with large bubbles
- Completely liquid
- Medium-stiff peaks that are glossy but not dry (Correct answer)
- Overwhipped and grainy
Correct answer: Medium-stiff peaks that are glossy but not dry
Glossy medium-stiff peaks hold air yet blend smoothly; dry, overwhipped whites break into clumps.
Question 2: What causes the hollow tunnels sometimes found inside muffins?
- Using paper liners
- Overmixing the batter, which develops gluten and traps large gas channels (Correct answer)
- Baking in a dark pan
- Adding too many blueberries
Correct answer: Overmixing the batter, which develops gluten and traps large gas channels
Overworked muffin batter forms gluten strands that channel gas into tunnels instead of an even crumb.
Question 3: Why is chocolate tempered before being used for dipped candies?
- Tempering removes all the sugar
- Tempering makes chocolate taste less bitter
- Tempering raises the melting point above 200°F
- Tempering aligns cocoa butter crystals for snap, shine, and no gray bloom (Correct answer)
Correct answer: Tempering aligns cocoa butter crystals for snap, shine, and no gray bloom
Proper tempering forms stable beta crystals in the cocoa butter, giving a glossy finish and clean snap.
Question 4: In high-altitude baking, which adjustment is typically recommended?
- Slightly reduce leavening and sugar while increasing liquid (Correct answer)
- Double the baking powder
- Halve the oven temperature
- Eliminate eggs from the recipe
Correct answer: Slightly reduce leavening and sugar while increasing liquid
Lower air pressure makes gases expand faster, so less leavening and more liquid prevent collapse and dryness.
Question 5: What is the difference between active dry yeast and instant yeast?
- Instant yeast only works in sourdough
- Active dry yeast contains baking powder
- Instant yeast can be mixed directly into flour, while active dry is usually dissolved in warm water first (Correct answer)
- Instant yeast must be frozen before use
Correct answer: Instant yeast can be mixed directly into flour, while active dry is usually dissolved in warm water first
Instant yeast has finer granules that hydrate quickly in the dough, skipping the separate proofing step.
Question 6: A pastry cream turns lumpy after cooking. What step most likely went wrong?
- The eggs were not tempered and scrambled when hot milk was added too fast (Correct answer)
- Too much vanilla was used
- The cornstarch was sifted
- The milk was whole instead of skim
Correct answer: The eggs were not tempered and scrambled when hot milk was added too fast
Adding hot milk to eggs without gradual tempering cooks the eggs into lumps instead of a smooth custard.
Question 7: Why do bakers use unsalted butter in most pastry recipes?
- It melts at a much higher temperature
- It contains more water than salted butter
- It is required for browning
- It lets them control the exact amount of salt in the recipe (Correct answer)
Correct answer: It lets them control the exact amount of salt in the recipe
Salt levels vary between salted butter brands, so unsalted butter keeps seasoning precise and consistent.
