CCC Baking and Pastry Operations 2 â Questions and Answers
Question 1: A chef notices their choux paste puffs collapse after being removed from the oven. What is the most likely cause?
- The pastries were underbaked, leaving too much internal moisture (Correct answer)
- Too much butter was used in the panade
- The oven temperature was too low at the start
- The eggs were added while the panade was too cool
Correct answer: The pastries were underbaked, leaving too much internal moisture
Underbaked choux retains steam and moisture inside, causing the structure to collapse as it cools.
Question 2: Which flour is most appropriate for producing a tender, fine-crumbed genoise sponge?
- Cake flour with approximately 7-9% protein (Correct answer)
- Bread flour with approximately 12-14% protein
- Whole wheat flour with high bran content
- Semolina flour milled from durum wheat
Correct answer: Cake flour with approximately 7-9% protein
Low-protein cake flour minimizes gluten development, yielding the delicate crumb desired in genoise.
Question 3: During lamination of croissant dough, the butter block breaks into shards instead of rolling out evenly. What condition most likely caused this?
- The butter was too cold and brittle relative to the dough (Correct answer)
- The dough was given too many turns
- The détrempe contained too much yeast
- The butter had too high a fat content
Correct answer: The butter was too cold and brittle relative to the dough
Butter that is too cold shatters during rolling instead of spreading in continuous layers with the dough.
Question 4: What is the primary function of adding an acid such as cream of tartar when whipping egg whites for meringue?
- It stabilizes the foam by slowing protein coagulation (Correct answer)
- It increases the volume by adding leavening gas
- It sweetens the meringue without added sugar
- It prevents the whites from absorbing fat
Correct answer: It stabilizes the foam by slowing protein coagulation
Acid lowers the pH, which stabilizes the egg white proteins and produces a more resilient foam.
Question 5: A pastry cook must temper dark chocolate for dipped confections. To which working temperature range should the chocolate be brought after seeding?
- Approximately 88-90°F (31-32°C) (Correct answer)
- Approximately 100-105°F (38-40°C)
- Approximately 70-72°F (21-22°C)
- Approximately 115-120°F (46-49°C)
Correct answer: Approximately 88-90°F (31-32°C)
Properly tempered dark chocolate is worked at about 88-90°F to maintain stable Form V cocoa butter crystals.
Question 6: In a lean bread dough, what role does the salt play beyond flavor?
- It tightens the gluten network and regulates yeast fermentation (Correct answer)
- It accelerates yeast activity to shorten proofing time
- It tenderizes the crumb by cutting gluten strands
- It adds moisture retention through hygroscopic starch bonding
Correct answer: It tightens the gluten network and regulates yeast fermentation
Salt strengthens gluten structure and slows yeast fermentation, giving controlled rise and better dough handling.
Question 7: Which method is correct for preparing a classic pùte sucrée?
- Cream the butter and sugar, add eggs, then gently incorporate flour (Correct answer)
- Cut cold butter into flour until pea-sized, then add ice water
- Boil water and butter, then beat in flour and eggs over heat
- Whip whole eggs with sugar to ribbon stage, then fold in flour
Correct answer: Cream the butter and sugar, add eggs, then gently incorporate flour
Pùte sucrée uses the creaming method, producing a sweet, cookie-like tart dough with a tender crumb.
