Cooking Lessons Meat and Poultry Cookery 2 — Questions and Answers
Question 1: What is the minimum safe internal temperature for cooking ground beef, according to USDA guidelines?
- 160°F (71°C) (Correct answer)
- 145°F (63°C)
- 135°F (57°C)
- 165°F (74°C)
Correct answer: 160°F (71°C)
Ground beef must reach 160°F because grinding distributes surface bacteria throughout the meat.
Question 2: Which cooking method is best suited for a tough, collagen-rich cut like beef chuck?
- Braising (Correct answer)
- Grilling over high heat
- Stir-frying
- Broiling
Correct answer: Braising
Braising uses low, moist heat over time to convert collagen into gelatin, tenderizing tough cuts.
Question 3: Why should a roasted whole chicken rest for 10-15 minutes before carving?
- To allow juices to redistribute through the meat (Correct answer)
- To let the skin become crispier
- To lower the bacteria count
- To make the bones easier to remove
Correct answer: To allow juices to redistribute through the meat
Resting lets muscle fibers relax and reabsorb juices, so less moisture is lost when carving.
Question 4: What does the term 'frenching' mean when preparing a rack of lamb?
- Scraping meat and fat from the ends of the rib bones (Correct answer)
- Marinating the meat in wine
- Tying the roast with butcher's twine
- Removing the entire bone from the rack
Correct answer: Scraping meat and fat from the ends of the rib bones
Frenching exposes the rib bones by scraping them clean for an elegant presentation.
Question 5: Which pigment is primarily responsible for the pink color sometimes seen in fully cooked smoked turkey?
- Myoglobin reacting with smoke gases (Correct answer)
- Hemoglobin from residual blood
- Carotene from the feed
- Melanin in the skin
Correct answer: Myoglobin reacting with smoke gases
Nitrogen compounds in smoke bind with myoglobin, fixing a pink color even at safe temperatures.
Question 6: A chef wants a deeply browned crust on a beef tenderloin steak. Which technique should be used first?
- Pat the steak dry and sear in a very hot pan (Correct answer)
- Poach the steak gently in butter
- Cover the steak while cooking over low heat
- Rinse the steak under cold water before cooking
Correct answer: Pat the steak dry and sear in a very hot pan
Surface moisture prevents browning, so drying the steak and using high heat promotes the Maillard reaction.
Question 7: What is the main food safety risk of stuffing a whole turkey before roasting?
- The stuffing may not reach 165°F before the meat overcooks (Correct answer)
- The stuffing absorbs too much fat
- The turkey skin will not brown
- The bones may splinter into the stuffing
Correct answer: The stuffing may not reach 165°F before the meat overcooks
Stuffing inside the cavity heats slowly and can harbor bacteria if it fails to reach 165°F.
