PCC Culinary Techniques & Cooking Methods 2 — Questions and Answers
Question 1: Which technique involves cooking food sealed in an airtight plastic bag submerged in a precisely temperature-controlled water bath?
- Confit
- Sous vide (Correct answer)
- Bain-marie
- Poaching
Correct answer: Sous vide
Sous vide uses vacuum-sealed bags in a temperature-controlled water bath to cook food evenly and retain moisture.
Question 2: When making a pan sauce, what is the technique of using liquid to dissolve browned food particles stuck to the pan called?
- Reduction
- Deglazing (Correct answer)
- Mounting
- Sweating
Correct answer: Deglazing
Deglazing involves adding liquid (wine, stock, or water) to a hot pan to lift the fond (browned bits), forming the base of a pan sauce.
Question 3: A chef wants to achieve a crispy crust on fish without overcooking it. Which dry-heat method is most appropriate?
- Steaming
- Poaching
- Sautéing (Correct answer)
- Braising
Correct answer: Sautéing
Sautéing uses high heat with minimal fat to quickly cook fish, developing a golden crust while preserving a moist interior.
Question 4: What is the primary purpose of blanching vegetables before freezing them?
- To add color
- To inactivate enzymes that cause deterioration (Correct answer)
- To remove excess water
- To add flavor
Correct answer: To inactivate enzymes that cause deterioration
Blanching briefly in boiling water inactivates enzymes that cause color loss, off-flavors, and texture deterioration during freezing.
Question 5: Which of the following best describes the 'carryover cooking' phenomenon?
- Food continues cooking from residual heat after being removed from the heat source (Correct answer)
- Flavor transfers from marinade into meat during cooking
- Heat moves from the outside to the inside of food during roasting
- Steam generated inside the oven continues the cooking process
Correct answer: Food continues cooking from residual heat after being removed from the heat source
Carryover cooking occurs when food continues to cook from stored internal heat after it is removed from the heat source, typically raising internal temperature 5–15°F.
Question 6: A classic hollandaise sauce breaks. Which technique can be used to rescue it?
- Whisk in cold water and return to heat
- Slowly whisk the broken sauce into a fresh egg yolk (Correct answer)
- Add heavy cream and blend vigorously
- Re-emulsify by adding more butter rapidly
Correct answer: Slowly whisk the broken sauce into a fresh egg yolk
A broken hollandaise can be rescued by slowly whisking the broken sauce into a fresh, lightly beaten egg yolk in a clean bowl to re-establish the emulsion.
Question 7: When braising a tough cut of meat, the long moist-heat cooking process primarily converts which connective tissue into gelatin?
- Actin
- Myosin
- Collagen (Correct answer)
- Elastin
Correct answer: Collagen
Collagen, abundant in tough cuts, breaks down into gelatin during long, slow moist-heat cooking, creating tender meat and a rich, silky sauce.
