Meat, Poultry, Fish and Seafood Preparation
Meat, Poultry, Fish and Seafood Preparation tests structure, doneness, fabrication and safety across the protein groups. Questions ask you to identify cuts and species, explain ageing and rigor, give core temperatures, and choose the correct preparation and handling for each product.
Meat structure and ageing
- Muscle fibre, connective tissue (collagen and elastin) and fat. Collagen softens with moist heat; elastin does not.
- Rigor mortis resolves in 24–48 hours; ageing for 14–28 days improves tenderness and flavour, with dry ageing losing more trim.
- Primals are broken into sub-primals and portions by seam and knife, not saw.
- Doneness: rare 50–52 °C, medium rare 55–57 °C, medium 60–63 °C, well done 71 °C and above. Rest 5–20 minutes; carryover adds 3–8 °C.
Poultry
- Cook to 74 °C in the thickest part of the thigh; juices run clear and the joint moves freely.
- Campylobacter and salmonella risks: dedicated board, never wash raw chicken, thaw in the fridge.
- Techniques: trussing, spatchcocking, ballotine, brining for moisture.
Fish and seafood
- Round fish (salmon, cod) versus flat fish (sole, turbot); white versus oily; cook to 60–63 °C.
- The 10-minute rule: approximate cooking time in minutes at high heat equals thickness in centimetres times ten.
- Freshness: eyes, gills, belly wall, scales, rigor. Oily fish spoil fastest.
- Crustaceans bought live or cooked, with a tail that snaps back; molluscs must be closed, and any that stay open after cooking are discarded.
- Hazards: scombrotoxin in tuna and mackerel, PSP in bivalves, parasites in raw freshwater fish, which requires freezing first.
Worked example
20 kg of beef topside is roasted at 160 °C for medium rare. Target core is 56 °C, and carryover adds about 4 °C during a 20-minute rest, so the joint is pulled at 52 °C. Probe the centre of the thickest end, not the fat cap. Yield after trim and shrinkage is about 80 %, giving 16 kg; at 180 g portions that is 88 portions.
Traps that cost marks
- Cooking poultry to 65 °C and calling it done.
- Thawing fish on the bench.
- Poking fish repeatedly and letting juices escape.
- Serving shellfish that failed to open during cooking.
