CCA CCA Baking & Pastry Fundamentals 2 — Questions and Answers
Question 1: What is the primary difference between puff pastry and croissant dough?
- Puff pastry uses yeast; croissant dough does not
- Croissant dough contains yeast (is a laminated yeast dough); puff pastry relies solely on steam for leavening (Correct answer)
- Puff pastry is richer than croissant dough
- They are made using the same technique
Correct answer: Croissant dough contains yeast (is a laminated yeast dough); puff pastry relies solely on steam for leavening
Both are laminated doughs, but croissant dough is enriched with yeast that provides biological leavening in addition to the steam leavening from butter layers, while puff pastry uses only steam.
Question 2: What is tempering chocolate?
- Melting and cooling chocolate to specific temperatures to stabilize cocoa butter crystals for a glossy, snapping finish (Correct answer)
- Adding cream to melted chocolate
- Mixing chocolate with tempered eggs
- Storing chocolate at room temperature
Correct answer: Melting and cooling chocolate to specific temperatures to stabilize cocoa butter crystals for a glossy, snapping finish
Tempering chocolate involves melting it and carefully cooling it through specific temperature stages to encourage the formation of stable Form V cocoa butter crystals, resulting in a glossy sheen and crisp snap.
Question 3: Which fat produces the flakiest pie crust?
- Olive oil
- Butter
- Shortening
- Lard (Correct answer)
Correct answer: Lard
Lard produces the flakiest pie crusts because its large fat crystals create distinct flaky layers and its plasticity at room temperature makes it easy to work with.
Question 4: What is the difference between a soft peak and a stiff peak when whipping cream or egg whites?
- Soft peaks fold over when the whisk is lifted; stiff peaks stand straight up and hold their shape (Correct answer)
- Soft peaks are used for savory dishes; stiff peaks for sweet
- There is no practical difference
- Stiff peaks are grainy; soft peaks are smooth
Correct answer: Soft peaks fold over when the whisk is lifted; stiff peaks stand straight up and hold their shape
Soft peaks fold over gently when the beater is lifted, while stiff peaks hold a firm, upright shape, and the stage used depends on the application in the recipe.
Question 5: What is the purpose of 'folding' in pastry techniques?
- To deflate batter for a denser texture
- To gently incorporate a lighter, airy mixture into a denser one without losing volume (Correct answer)
- To cool down a hot mixture quickly
- To combine fat and flour for pie dough
Correct answer: To gently incorporate a lighter, airy mixture into a denser one without losing volume
Folding is a gentle technique using a spatula to incorporate airy mixtures like whipped cream or egg whites without deflating the trapped air that provides lightness.
Question 6: What leavening mechanism is responsible for the rise in cream puffs (choux pastry)?
- Yeast fermentation
- Chemical leaveners (baking powder)
- Steam from the high water content of the dough (Correct answer)
- Whipped egg whites
Correct answer: Steam from the high water content of the dough
Choux pastry relies entirely on steam leavening — the high water content in the dough converts to steam in the hot oven, causing the pastry to puff up dramatically.
