Understanding core temperature - the most honest doneness
Why core temperature beats any timer, which values are safe and how to measure it correctly.
Core temperature is the only number that truly tells you what is happening in the middle of your food. The times printed in recipes are approximations: they depend on the thickness of the cut, the starting temperature, the weather and your device. The temperature at the core depends on none of that - it is the truth.
Why time lies and temperature does not
Two steaks of equal weight cook at different speeds if one is flat and one is thick. Take the meat straight from the fridge instead of the counter, and everything shifts again. A thermometer in the core makes these variables irrelevant: you grill toward a target, not toward a clock.
Safe reference values
These are food-safe guide values - always readable with a source inside Glutkern, shown in °C or °F depending on your unit system:
- Beef, medium: around 54 to 57 °C at the core
- Pork, well done: at least 63 °C, then rest
- Poultry: at least 72 to 74 °C, no compromise
- Mince and burgers: 70 °C and above, throughout
Poultry and minced meat forgive no experiments: here the minimum temperature matters, not the look.
Measuring it right
Insert the probe into the centre of the thickest part, avoiding bone or fat seams - both distort the reading. Measure just before the expected target, not constantly, so less juice escapes.
Account for carry-over: a thick cut rises another two to four degrees while resting. So take it off the heat just short of the target.
How Glutkern helps
The cooking guide gives you doneness levels with a safety note and a quick timer for every cut. Via “What are you grilling?” you get core temperature, matching recipes and sides in one place - tuned to your devices.
