ACF Culinary Techniques & Food Preparation 4 — Questions and Answers
Question 1: What is the term for the process of cooking pasta, rice, or vegetables briefly in boiling water then immediately cooling in ice water?
- Parboiling
- Blanching (Correct answer)
- Steeping
- Sweating
Correct answer: Blanching
Blanching involves briefly boiling food then shocking it in ice water to stop cooking, preserve color, and set texture.
Question 2: In sauce making, what does 'mounting with butter' (monter au beurre) accomplish?
- Thickens the sauce with a roux
- Adds richness, sheen, and body by emulsifying cold butter into a finished sauce (Correct answer)
- Caramelizes the sauce for deeper flavor
- Reduces the sauce to concentrate flavor
Correct answer: Adds richness, sheen, and body by emulsifying cold butter into a finished sauce
Mounting with butter finishes a sauce by whisking cold butter pieces in off-heat, creating a glossy, rich, emulsified texture.
Question 3: Which cooking technique involves cooking food gently in fat at low temperatures (140°F–190°F) for an extended period?
- Deep frying
- Confit (Correct answer)
- Braising
- Pan-frying
Correct answer: Confit
Confit is the technique of slow-cooking food fully submerged in fat at low temperatures, traditionally used for duck legs.
Question 4: A recipe calls for a sachet d'épices. Which combination of ingredients would correctly make one?
- Onion, carrot, celery, and leek
- Bay leaf, thyme, peppercorns, parsley stems, and garlic wrapped in cheesecloth (Correct answer)
- Tarragon, chervil, chives, and parsley tied in a bundle
- Tomato paste, mirepoix, and herbs simmered together
Correct answer: Bay leaf, thyme, peppercorns, parsley stems, and garlic wrapped in cheesecloth
A sachet d'épices is a cheesecloth bag containing bay leaf, thyme, peppercorns, parsley stems, and garlic used to flavor stocks and sauces.
Question 5: What term describes the carryover cooking that occurs in a large roast after it is removed from the oven?
- Residual heat transfer
- Carryover cooking (Correct answer)
- Conduction diffusion
- Resting equilibration
Correct answer: Carryover cooking
Carryover cooking refers to the continued rise in internal temperature after food is removed from the heat source due to stored thermal energy.
Question 6: Which of the following describes the 'nappe' consistency of a sauce?
- The sauce pools freely on a plate
- The sauce coats the back of a spoon and holds a line drawn through it (Correct answer)
- The sauce is thick enough to hold a soft peak
- The sauce sets firm when cooled
Correct answer: The sauce coats the back of a spoon and holds a line drawn through it
Nappe consistency means the sauce is thick enough to coat the back of a spoon and a line drawn through it holds cleanly.
Question 7: When sautéing, the pan should be preheated before adding fat. What problem does this prevent?
- Burning the fat before food is added
- Food sticking to the pan by preventing protein bonding to cool metal (Correct answer)
- Uneven heat distribution across the pan surface
- Excess oil absorption by the food
Correct answer: Food sticking to the pan by preventing protein bonding to cool metal
A properly preheated pan with hot fat prevents sticking because proteins form bonds with other proteins rather than with the cooler pan surface.
