PCC Culinary Techniques & Cooking Methods 3 — Questions and Answers
Question 1: What distinguishes a braise from a stew in terms of the amount of liquid used?
- A braise uses more liquid than a stew
- A braise uses just enough liquid to partially cover the protein, while a stew fully submerges the food (Correct answer)
- A stew uses wine while a braise uses stock
- They are identical methods with different names
Correct answer: A braise uses just enough liquid to partially cover the protein, while a stew fully submerges the food
In a braise, liquid partially covers the larger cut of meat, while in a stew, the smaller, cut-up pieces are fully submerged in liquid.
Question 2: Which emulsification method is used to make a classic mayonnaise?
- Temporary emulsion by shaking oil and vinegar
- Permanent emulsion using egg yolk lecithin as an emulsifier (Correct answer)
- Semi-permanent emulsion stabilized by mustard alone
- Suspension created by high-speed blending without an emulsifier
Correct answer: Permanent emulsion using egg yolk lecithin as an emulsifier
Mayonnaise is a permanent emulsion where lecithin in egg yolk acts as the emulsifier, stabilizing oil droplets dispersed in the acidic water phase.
Question 3: A chef is roasting a chicken and uses a technique where the bird is turned multiple times during cooking. What is the main benefit?
- It speeds up cooking time by 50%
- It ensures even browning and helps baste the bird in its own juices (Correct answer)
- It prevents carryover cooking
- It reduces the need for resting time
Correct answer: It ensures even browning and helps baste the bird in its own juices
Turning the bird allows all surfaces to spend time closer to the heat source, promoting even browning (Maillard reaction) and self-basting.
Question 4: What is the difference between shallow-frying and deep-frying?
- Shallow-frying uses water-based liquids while deep-frying uses oil
- In shallow-frying, food is only partially submerged in oil and must be flipped; in deep-frying, food is fully submerged (Correct answer)
- Deep-frying requires lower temperatures than shallow-frying
- Shallow-frying is only suitable for vegetables
Correct answer: In shallow-frying, food is only partially submerged in oil and must be flipped; in deep-frying, food is fully submerged
Shallow-frying uses enough oil to reach halfway up the food, requiring it to be flipped, while deep-frying fully submerges food for even, simultaneous cooking on all sides.
Question 5: When making pasta dough, gluten development is essential. Which technique promotes gluten development?
- Adding fat early in the mixing process
- Resting the dough uncovered in the refrigerator
- Kneading the dough repeatedly (Correct answer)
- Mixing the dough as briefly as possible
Correct answer: Kneading the dough repeatedly
Kneading aligns and strengthens gluten networks by repeatedly stretching and folding the dough, creating the elasticity needed for pasta.
Question 6: A chef needs to quickly cool a large batch of stock for food safety. Which method is most appropriate?
- Leave it at room temperature until cool, then refrigerate
- Place the pot in an ice bath and stir frequently (Correct answer)
- Divide into large containers and refrigerate immediately
- Cover tightly and place in the freezer
Correct answer: Place the pot in an ice bath and stir frequently
An ice bath with frequent stirring rapidly drops the temperature through the danger zone (40–140°F), meeting food safety guidelines for cooling.
Question 7: What cooking technique uses indirect heat in a covered vessel with aromatics to cook vegetables or lean meats in their own moisture?
- Steaming
- Étuvée (smothering) (Correct answer)
- Poaching
- En papillote
Correct answer: Étuvée (smothering)
Étuvée (smothering) cooks food covered over low heat using only the moisture naturally present in the ingredients, concentrating flavors.
