Rib-Eye Roast: Carryover, Resting and a Late Temperature Check
At 15:30, a 5.4 kg boneless rib-eye roast is seasoned, trussed, and placed on a rack in a 120°C convection oven for a 19:00 service. The chef wants medium-rare: 54°C after carryover. At 17:45, the probe in the thickest part reads 49°C and the oven reads 118°C. The roast is 12 cm thick at its center. The chef needs to hold it for 45 minutes before carving for 60 guests; the first course is at 19:00. Available are a hot-holding cabinet set at 60°C, a low oven at 70°C, and an ice bath. The kitchen uses a calibrated probe thermometer. The previous roast of the same size pulled at 52°C carried over to 60°C.
1. Decide whether to pull the roast now, continue cooking, or hold it. Show the carryover reasoning and the timing.

The previous roast is the key evidence: pulling at 52°C carried over to 60°C, an 8°C rise. That is large for a 5.4 kg roast, but it shows the oven and resting conditions are producing significant carryover. If this roast is pulled at 49°C, an 8°C rise would reach 57°C, which is medium, not medium-rare. However, carryover depends on the final oven temperature, resting environment, and thickness. At 120°C oven temperature, a more typical rise is 4–6°C, giving 53–55°C.
The roast should be pulled now at 49°C and rested tented at room temperature, not placed in the 60°C cabinet immediately. That gives the best chance of landing at 53–55°C. If it is left in the oven to 52°C, the previous result suggests it will overshoot to about 60°C. Pull now, rest 20–25 minutes, then hold in a 50–55°C environment if available. The 60°C cabinet and 70°C oven are both too hot for a 45-minute hold.
2. Where and how should the roast be probed, and what would you do if the center reads 58°C at 18:30?

Probe the geometric center of the thickest part, avoiding fat, bone, and the roast's exterior. Use a calibrated probe, insert it fully, wait for the reading to stabilize, and take at least two readings in different thick sections. A single reading near the surface or near a fat seam will be misleading. Record the readings and the time.
If the center reads 58°C at 18:30, the roast is already medium, not medium-rare. Do not try to cool it in an ice bath; that will make the exterior cold and the texture worse. Serve it as a medium roast, carve thinner slices, and use the ends for guests who want medium-well or well-done. If medium-rare is contractually required, the honest options are to offer a supplementary pan-seared portion or to inform the service team of the change. The chef should also note that the 49°C pull was correct in principle but the resting environment or probe placement added more carryover than expected.
3. Choose and justify a holding method for the 45 minutes before carving.

The 60°C cabinet is too hot for a 45-minute hold. A 5.4 kg roast placed in a 60°C cabinet will continue to rise internally, possibly by 5–8°C, and will dry at the surface. The 70°C oven is worse. The ice bath is not appropriate for a whole roast because it cools the exterior and creates uneven texture.
The best method is to rest the roast uncovered for 10 minutes to stop surface steaming, then tent loosely with foil and hold at ambient kitchen temperature for up to 30 minutes, or in a holding cabinet set at 50–55°C if the kitchen has one. Check the core temperature at 18:20 and again at 18:40. If it falls below 50°C, a brief hold in the 60°C cabinet is acceptable, but monitor every 10 minutes. For service, carve against the grain and keep slices in hot jus, not in a hot oven. The priority is to protect the 54°C target, not merely to keep the meat hot.
