Why carryover matters for garden harvest cooking
Garden produce often finishes cooking off-heat because the outer layers stay hotter than the center. This calculator estimates that “carryover rise” so you can pull at a safer point, rest with control, and still hit your preferred serving temperature.
Key drivers the calculator uses
Carryover increases with higher heat-source temperature, thicker pieces, larger batch weight, and better insulation. It decreases when you slice, stir, or expose more surface area. The method selector changes the baseline heat transfer, while the food group adjusts for moisture and density.
Rest time is not linear
Most carryover happens early, then levels off as temperatures equalize. The model applies an exponential approach-to-peak so a 5–10 minute rest can deliver most of the rise, while extending to 20 minutes typically adds only a smaller extra gain unless the batch is very thick.
Cover choices and cooling tradeoffs
Foil tenting and lidded pans slow cooling, but they also preserve residual heat, pushing peak higher. Uncovered resting sheds heat quickly and may prevent overshoot for delicate vegetables. Use the “end-of-rest” target mode when you care about plating temperature rather than peak.
Example data you can compare against
The table below shows sample scenarios. As a quick reference, many roasted starchy vegetables land around +4 to +7 °C rise with a 10–15 minute tented rest, while steamed vegetables often stay near +1 to +3 °C with uncovered resting. Use your thermometer log to tune your settings.
| Scenario | Settings | Typical outcome |
|---|---|---|
| Roasted potatoes | 200 °C source, 4 cm thick, foil tent, 12 min | Peak rises about +4 to +7 °C |
| Steamed carrots | 100 °C source, 2.5 cm thick, uncovered, 6 min | Peak rises about +1 to +3 °C |
| Insulated beet batch | 190 °C source, 6 cm thick, insulated, 15 min | Peak rises about +5 to +9 °C |
