Scenario 1
A 40°F steak targeting 145°F with 5°F assumed carryover has a modeled 100°F rise to the pull point. At 0.6–1.0°F/min the heat stage spans about 100–167 minutes before fixed stages.

What is a Reverse Sear Timing Planner?
A Reverse Sear Timing Planner plan a reverse-sear heating window from user-observed rates, carryover, searing, resting, and an explicit safety-temperature check. It exposes the input basis and returns scenarios instead of presenting a universal BBQ rule as certainty.
Outdoor cooking combines variable food, heat, equipment and environment. Shape, thickness, starting temperature, airflow, weather, recovery after opening, fuel condition, instrument placement and operator decisions can materially change a session. Safety-sensitive measurements also have a source and jurisdiction: U.S. consumer guidance, a retail model code, an equipment manual and an adopted local rule are not interchangeable.
This tool deliberately separates planning arithmetic from verification. A schedule cannot declare meat done. Fuel quantity cannot prove that a smoker held temperature. A cold displacement measurement cannot remove fryer hazards. A timestamp comparison cannot recover food after an exceeded limit. Formulation arithmetic cannot validate a cure process or establish shelf stability.
Use the output as a documented checkpoint. Retain the entered units, scope, source edition and instrument observations so another person can reproduce the calculation. When conditions differ, recalculate rather than carrying forward a precise-looking answer.
How It Works
Temperature rise to a modeled pull point is divided by a low and high observed heating rate, then sear, rest and buffer minutes are added. Input validation rejects missing, reversed, unsupported or physically impossible values before calculation. The scenario chart and table reveal sensitivity while the warning and next-action text state what still requires direct measurement or professional review.
pull °F = target °F − assumed carryover °F; minutes = temperature rise ÷ observed rate
Example Calculations
Scenario 2
A faster observed rate shortens the schedule, but the cook should probe early because rate may change near the end.
Scenario 3
A poultry target below its applicable entered minimum creates a warning rather than a time-only assurance.
Common Applications
- • Prepare a documented backyard or catered-event plan before equipment is hot.
- • Compare optimistic, typical and conservative assumptions in one record.
- • Identify a fill, temperature, source-limit or equipment constraint early.
- • Convert measured burn rates or temperature observations into usable quantities.
- • Train helpers on checkpoints without implying the calculator certifies their work.
- • Review actual results after a cook and improve the next measured plan.
Practical Tips
Calibrate thermometers and scales at appropriate intervals, keep measurement locations consistent, and write down units. Read every product label and equipment manual. Keep raw food cold and separated, never partially cook for an uncontrolled later finish, and do not rely on color. Where commercial service or curing is involved, obtain review from the responsible authority and a qualified food-safety professional.
Frequently Asked Questions
What does this reverse sear timing planner establish?
It performs transparent arithmetic against the measurements, assumptions, and selected reference entered. It does not certify safe food, equipment suitability, legal compliance, pathogen control, doneness, or shelf stability. Keep the result with its assumptions and verify the real process independently.
Can elapsed time replace a food thermometer?
No. Cooking estimates and example time ranges are planning aids only. Use a calibrated thermometer in the appropriate thickest or USDA-specified locations, confirm the applicable current minimum for the food, and keep recipe tenderness targets separate from safety minimums.
Why are defaults editable?
Cookers, food geometry, weather, observed burn rates, equipment limits, formulations, and local rules differ. Defaults make the interface usable but are not claims about your situation. Replace them with measured values, the appliance manual, the product label, and the rule adopted by your jurisdiction.
Which authority should I follow?
USDA FSIS guidance applies to U.S. consumer handling. The FDA Food Code is a model for retail and food service, not automatically the law everywhere. Manufacturer instructions and the rule adopted by the actual state, local, tribal, territorial, or national jurisdiction may be more restrictive.
What should I record?
Record dates, units, instrument identification, calibration checks, measurement locations, timestamps, cooker settings, ambient conditions, product labels, package sizes, source edition, equipment model, actual outcome, and any intervention. Do not average readings from different food locations or times to manufacture a passing checkpoint.
What happens when an input is outside guidance?
The calculator reports an error, disqualification, unknown status, or outside-selected-guidance message. It does not silently clamp a high curing target, reset an exceeded clock, infer missing oil volume, or convert an unsupported process into a superficially similar one.
