CMC Baking, Pastry, & Garde Manger Arts 2 — Questions and Answers
Question 1: When laminating croissant dough, what is the purpose of the 'lock-in' stage before the first fold?
- To activate the yeast before layering
- To encase the butter block completely within the dough so it does not escape during rolling (Correct answer)
- To chill the dough below freezing to prevent gluten development
- To rest the dough so the fat absorbs into the flour
Correct answer: To encase the butter block completely within the dough so it does not escape during rolling
The lock-in stage encases the butter block within the dough détrempe, preventing butter from breaking through during the rolling and folding process.
Question 2: A pastry chef notices that a baked choux puff collapses after removal from the oven. What is the most likely cause?
- The oven temperature was too high during baking
- The choux was underbaked and retained too much moisture (Correct answer)
- Too much egg was added to the paste
- The piping tip used was too small
Correct answer: The choux was underbaked and retained too much moisture
Underbaked choux contains excess steam that condenses upon cooling, causing the shell to collapse; the puff must be dried out fully in the oven.
Question 3: In garde manger, which binding agent is most appropriate for creating a firm, sliceable terrine served cold?
- Arrowroot
- Gelatin (Correct answer)
- Cornstarch
- Xanthan gum
Correct answer: Gelatin
Gelatin sets firmly when chilled and provides the clean, sliceable texture required for cold terrines and aspic-bound preparations.
Question 4: What is the Baker's Percentage, and how is it calculated?
- The ratio of flour to water expressed as a decimal
- Each ingredient's weight expressed as a percentage of the total flour weight (Correct answer)
- The percentage of gluten in the flour used
- The ratio of leavening to total dough weight
Correct answer: Each ingredient's weight expressed as a percentage of the total flour weight
Baker's Percentage expresses each ingredient's weight as a percentage of the flour weight, always setting flour at 100% regardless of total yield.
Question 5: A pastry cook is tempering dark chocolate for enrobing. After melting to 50°C, the chocolate is cooled to 27°C and then rewarmed to which working temperature?
- 29–32°C (Correct answer)
- 35–38°C
- 24–26°C
- 40–42°C
Correct answer: 29–32°C
Dark chocolate is tempered to a working temperature of 29–32°C to maintain stable Form V (beta) crystals for a glossy, snappy finish.
Question 6: In a classic garde manger mise en place, what distinguishes a mousseline forcemeat from a basic straight forcemeat?
- Mousseline is cooked at higher temperatures to achieve a firmer texture
- Mousseline contains heavy cream and whipped egg whites, producing a lighter, more delicate texture (Correct answer)
- Mousseline uses a higher fat-to-protein ratio through added lard
- Mousseline omits the panada and relies solely on emulsification
Correct answer: Mousseline contains heavy cream and whipped egg whites, producing a lighter, more delicate texture
Mousseline forcemeat incorporates heavy cream and sometimes whipped egg whites, yielding an exceptionally light and delicate texture compared to straight or country-style forcemeats.
Question 7: Which sugar cooking stage reaches approximately 160°C (320°F) and is characterized by the sugar just beginning to turn light golden?
- Soft ball
- Hard crack
- Light caramel (Correct answer)
- Firm ball
Correct answer: Light caramel
Light caramel begins at around 160°C as sucrose starts to decompose and develop color, marking the onset of caramelization.
