Guide
Use a clean probe in the thickest part of the food and judge safety by core temperature plus holding time. In UK guidance, 70°C for 2 minutes is a standard reference combination.
Use an instant-read thermometer for spot checks and an oven-safe leave-in probe for continuous monitoring. Check the maker's temperature limits before exposing a probe, cable or display to an oven, grill or hot oil.
Aim for the thickest part and keep the sensing area away from bone, gristle, the tray and the oven wall. For thin food, insert from the side so more of the sensor sits inside the centre.
The FSA cites 70°C for 2 minutes and equivalent combinations such as 75°C for 30 seconds. A food thermometer temperature guide should always pair the number with the required hold time.
Bacteria can be present beyond the surface in poultry, minced products, sausages and rolled joints. Confirm the coldest spot has reached the appropriate combination rather than relying only on browning.
Stir dishes where possible, allow standing time after microwave heating and check different areas. The FSA advises reheating leftovers only once.
Clean the sensing stem after every use and between raw and cooked food. If readings seem implausible, compare the unit using the calibration method in its manual rather than adjusting it blindly.
Common questions
Measure the thickest, coldest part of the food, avoiding bone and cookware. Take several readings in large or uneven items.
The FSA uses 70°C for 2 minutes as a standard reference and lists equivalent hotter, shorter combinations. Product instructions can require other targets.
Only an oven-safe leave-in model should remain in place. Remove an ordinary instant-read thermometer after each check.
Follow the maker's calibration or accuracy-check instructions. Ice-point checks require correct ice-to-water proportions and may not suit every model.
Keep exploring
An instant-read thermometer suits quick checks; a leave-in or wireless probe is better for tracking a roast without repeatedly opening the oven.
Pick a folding digital thermometer for rapid checks or a leave-in digital probe for alarms during a roast. Accuracy and sensing-tip placement matter more than extra presets.
Thermapen ONE is our top all-round pick for fast spot checks. ThermoPro TP19H is the simpler alternative, while DOT and MEATER Pro suit cooks who need continuous monitoring.
