ACF Culinary Techniques & Food Preparation 5 — Questions and Answers
Question 1: What is the purpose of resting meat after cooking before carving?
- To allow the exterior crust to soften
- To allow muscle fibers to relax and juices to redistribute throughout the meat (Correct answer)
- To bring the internal temperature down to a safe level
- To allow carryover cooking to raise the internal temperature further
Correct answer: To allow muscle fibers to relax and juices to redistribute throughout the meat
Resting allows contracted muscle fibers to relax and reabsorb juices, resulting in a moister, more evenly textured cut of meat.
Question 2: Which thickening agent is derived from seaweed and used to create firm, sliceable gels that melt at a higher temperature than gelatin?
- Arrowroot
- Agar-agar (Correct answer)
- Xanthan gum
- Carrageenan
Correct answer: Agar-agar
Agar-agar, derived from red algae, sets firmer than gelatin and holds its gel structure at room temperature, melting only above 185°F.
Question 3: A cook is preparing a pan sauce from the fond left in a sauté pan. What is the first step?
- Add cream and reduce
- Deglaze the pan with wine or stock to dissolve the caramelized drippings (Correct answer)
- Add butter and whisk to emulsify
- Season and strain the drippings
Correct answer: Deglaze the pan with wine or stock to dissolve the caramelized drippings
Deglazing dissolves the fond (caramelized drippings stuck to the pan) using liquid, which forms the flavorful base of a pan sauce.
Question 4: In charcuterie, what is the role of sodium nitrite (curing salt/pink salt) in meat preservation?
- Adds pink color only for visual appeal
- Inhibits Clostridium botulinum growth, prevents rancidity, and contributes to cured flavor and color (Correct answer)
- Acts as a tenderizer by breaking down muscle proteins
- Adjusts pH to prevent microbial growth through acidity
Correct answer: Inhibits Clostridium botulinum growth, prevents rancidity, and contributes to cured flavor and color
Sodium nitrite in curing salts is essential for inhibiting C. botulinum, preventing oxidative rancidity, and producing the characteristic cured pink color and flavor.
Question 5: Which cooking method best preserves water-soluble vitamins such as B vitamins and vitamin C in vegetables?
- Boiling in large amounts of water
- Steaming (Correct answer)
- Blanching then shocking
- Braising in broth
Correct answer: Steaming
Steaming preserves water-soluble vitamins best because the food never contacts water, minimizing nutrient leaching.
Question 6: What does the term 'en papillote' describe?
- Cooking food wrapped in parchment paper packets using steam generated from the food's own moisture (Correct answer)
- Cooking food wrapped in caul fat before roasting
- A method of deep-frying food encased in phyllo dough
- Cooking food in a sealed vacuum bag submerged in temperature-controlled water
Correct answer: Cooking food wrapped in parchment paper packets using steam generated from the food's own moisture
En papillote is a French technique of sealing food in parchment paper and baking it so the food steams in its own juices.
Question 7: When preparing an emulsified vinaigrette, which ingredient acts as the emulsifier to keep oil and vinegar combined?
- Salt
- Dijon mustard (due to its lecithin content) (Correct answer)
- Honey or sugar
- Black pepper
Correct answer: Dijon mustard (due to its lecithin content)
Dijon mustard contains lecithin and mucilage compounds that act as emulsifiers, bridging oil and water phases in vinaigrette.
