Carryover.

What it is. Residual heat continues cooking a protein 5–15°F after it leaves the heat source. A steak pulled from the pan at 125°F will finish at 130–135°F during its rest. Ignore this and your perfect medium-rare becomes gray medium on the cutting board. Every thick protein — steak, chop, roast, fish fillet — obeys this law.

Why It Works — The Science

Heat flows from hot to cold. During cooking, the protein's exterior is much hotter than its interior; the moment you pull it off heat, that exterior temperature begins equalizing inward. For a ¾-inch pork chop, carryover is ~5°F. For a 2-inch ribeye, ~10°F. For a 4-lb pork shoulder pulled from a 225°F smoker, up to 15°F.

How To Execute

• Know your target internal. E.g., medium-rare beef = 130–135°F. Write it down before the protein hits heat.
• Pull at target minus 5–10°F depending on thickness. Thin cuts shed little heat; thick cuts shed a lot.
• Tent loosely with foil — not airtight. A tight wrap traps steam and ruins the crust you just built.
• Rest: 5 min per inch of thickness is a safe floor. The bigger the cut, the longer it needs.
• Slice only after carryover plateaus. Then collect and pour the resting juices back over the meat.

Failure Modes

• Didn't pull early. Overcooked. The oven doesn't stop when the timer does — the meat doesn't either.
• Pulled too early. Still undercooked. Recoverable — return to heat for a quick finish, then rest.
• No rest. Juice pours onto the board, meat eats dry. The juice belongs in the muscle fibers, not on the cutting board.
• Tight wrap. Crust steams soft. Tent — don't seal.

Pair With

Critical for reverse sear — pull the slow-cook at 115–120°F for a 130°F target after the hard sear that follows. Also governs sous vide → sear transitions. Thin fish (<¾ inch) has little carryover and can be pulled closer to target; thick roasts have massive carryover and must come off the heat well before they look done.
