CFSP Kitchen Operations 4 — Questions and Answers
Question 1: A kitchen manager wants to reduce food costs. Which metric directly measures the ratio of food cost to food sales revenue?
- Labor cost percentage
- Food cost percentage (Correct answer)
- Prime cost ratio
- Contribution margin
Correct answer: Food cost percentage
Food cost percentage = (cost of food sold ÷ food sales) × 100, and is the primary metric for evaluating food purchasing and production efficiency.
Question 2: Which hazard is classified as a physical contaminant in food safety?
- Salmonella bacteria
- Pesticide residue on produce
- A metal fragment from a can opener (Correct answer)
- Mold toxins in stored grain
Correct answer: A metal fragment from a can opener
Physical contaminants are foreign objects — such as metal, glass, or bone fragments — that can cause injury if consumed.
Question 3: A commercial dishwasher uses hot water sanitizing. What is the minimum final rinse temperature required to sanitize dishes?
- 140°F (60°C)
- 160°F (71°C)
- 180°F (82°C) (Correct answer)
- 212°F (100°C)
Correct answer: 180°F (82°C)
High-temperature dishwashers must deliver a final rinse of at least 180°F (82°C) at the dish surface to achieve effective sanitization.
Question 4: In a scratch kitchen, which cooking method is best suited for producing a tender result from a tough, collagen-rich beef chuck roast?
- Sautéing over high heat for a short time
- Broiling at high temperature until medium-rare
- Braising low and slow in liquid (Correct answer)
- Steaming in a convection oven
Correct answer: Braising low and slow in liquid
Braising converts collagen in tough cuts to gelatin through long, moist-heat cooking at low temperatures, producing a tender result.
Question 5: A foodservice manager is conducting a menu engineering analysis. Items classified as 'Stars' are those that have:
- High profitability but low customer popularity
- Low profitability and low customer popularity
- High profitability and high customer popularity (Correct answer)
- Low profitability but high customer popularity
Correct answer: High profitability and high customer popularity
In menu engineering, 'Stars' are items with both high contribution margin (profitability) and high menu mix (popularity), making them the most desirable menu items.
Question 6: Which action is most appropriate when an employee reports to work showing symptoms of jaundice (yellowing of the skin/eyes)?
- Assign the employee to dishwashing duties only
- Restrict the employee from food handling and notify the health department (Correct answer)
- Allow the employee to work if they wear gloves
- Let the employee decide whether to stay based on how they feel
Correct answer: Restrict the employee from food handling and notify the health department
Jaundice may indicate hepatitis A or other serious transmissible conditions; the FDA Food Code requires exclusion from food handling and reporting to the regulatory authority.
Question 7: What is the purpose of a receiving log in kitchen operations management?
- To track employee attendance during deliveries
- To document incoming product details for accountability, quality control, and traceability (Correct answer)
- To record the number of portions prepared each shift
- To schedule vendor delivery windows
Correct answer: To document incoming product details for accountability, quality control, and traceability
A receiving log captures product name, quantity, date, temperature, condition, and vendor, enabling traceability in case of foodborne illness investigation.
