Even with the best thermometer, proper technique is essential for accurate temperature readings. The placement of the probe is crucial, as is understanding the nuances of different types of food.
Proper Probe Placement
The location where you insert the probe significantly impacts the accuracy of the reading. The general rule is to insert the probe into the thickest part of the food, avoiding bone, fat, or gristle.
- Meat: Insert the probe into the thickest part of the muscle, away from bone and fat. For roasts, probe from the side, reaching the center.
- Poultry: For whole birds, insert the probe into the thickest part of the thigh, avoiding the bone. For breasts, probe from the top, reaching the center.
- Fish: Insert the probe into the thickest part of the fillet.
- Ground Meat: Probe several areas to ensure the entire mass has reached a safe internal temperature.
- Casseroles and Other Dishes: Insert the probe into the center of the dish.
Considering Carryover Cooking
Carryover cooking refers to the phenomenon where food continues to cook after being removed from the heat source. The internal temperature can rise several degrees during this time, especially for larger cuts of meat.
To account for carryover cooking, remove the food from the heat when it is a few degrees below the desired final temperature. The residual heat will bring it up to the perfect doneness as it rests. The amount of carryover cooking varies depending on the size and density of the food, as well as the cooking temperature.
Calibrating Your Thermometer
Regular calibration ensures that your thermometer provides accurate readings. Over time, thermometers can drift out of calibration, leading to inaccurate temperature measurements.
The ice bath method is a simple and effective way to calibrate a thermometer. Fill a glass with ice and add water until it reaches the top. Submerge the thermometer probe into the ice water, ensuring it doesn’t touch the sides or bottom of the glass. After a few minutes, the thermometer should read 32°F (0°C). If it doesn’t, adjust the calibration according to the manufacturer’s instructions.
Boiling water can also be used to calibrate a thermometer. Submerge the probe in boiling water and wait for the reading to stabilize. At sea level, the thermometer should read 212°F (100°C). Adjust the calibration as needed. Keep in mind that the boiling point of water decreases with altitude, so you’ll need to adjust the target temperature accordingly.
Safe Minimum Internal Temperatures
Ensuring that food reaches a safe minimum internal temperature is paramount for preventing foodborne illnesses. The USDA provides guidelines for safe cooking temperatures for various types of food.
| Food | Minimum Internal Temperature |
| —————————— | —————————— |
| Ground Beef | 160°F (71°C) |
| Poultry (Chicken, Turkey) | 165°F (74°C) |
| Beef, Pork, Lamb (Steaks, Roasts) | 145°F (63°C) |
| Fish | 145°F (63°C) |
| Eggs | 160°F (71°C) |
These temperatures are minimums, and you may choose to cook some foods to a higher temperature based on personal preference. However, it is crucial to never cook below the recommended minimum to ensure food safety.

What is the best type of food thermometer to use for probing food, and why?
Digital instant-read thermometers are generally considered the best for probing food. They provide quick and accurate temperature readings, which is crucial for achieving precise doneness. Their slender probes minimize damage to the food, and the digital display eliminates guesswork, making them user-friendly for cooks of all skill levels.
While other thermometers like dial thermometers and leave-in thermometers have their uses, instant-read thermometers offer the best combination of speed, accuracy, and convenience for checking the internal temperature of various foods. This allows for on-the-spot adjustments during cooking, helping you avoid overcooking or undercooking.
Where is the best place to insert the thermometer probe into different types of meat for an accurate reading?
For accurate readings in larger cuts of meat like roasts and poultry, insert the thermometer into the thickest part, avoiding bone and fat. Aim for the center to get the most representative temperature. In thinner cuts like steaks and chops, insert the probe from the side, ensuring it reaches the center without touching the cooking surface.
When probing whole poultry, insert the thermometer into the thickest part of the thigh, away from the bone. Bone can conduct heat and give a falsely high reading. For ground meat patties, insert the probe through the side into the center of the patty. Correct placement is key to ensuring a safe and perfectly cooked meal.
How can I calibrate my food thermometer to ensure its accuracy?
The most common method for calibrating a food thermometer is the ice bath test. Fill a glass with ice and add water until the ice is covered. Immerse the thermometer probe into the ice water, making sure it doesn’t touch the sides or bottom of the glass. After a few minutes, the thermometer should read 32°F (0°C).
If your thermometer doesn’t read 32°F (0°C) in the ice bath, adjust it using the calibration nut (if it has one) until it does. If your thermometer doesn’t have a calibration nut, you may need to factor in the difference when checking food temperatures. For example, if it reads 34°F (1°C) in the ice bath, subtract 2°F (1°C) from your target temperature when cooking.
What is temperature “carryover” and how does it affect cooking?
Temperature carryover is the phenomenon where the internal temperature of food continues to rise after it’s removed from the heat source. This happens because the outer layers of the food retain heat, which gradually migrates towards the cooler center, increasing the internal temperature.
Understanding carryover is crucial for preventing overcooking. To account for it, remove the food from the heat source a few degrees below your target temperature. The carryover will bring the temperature up to the desired doneness as it rests. The amount of carryover varies depending on the size and density of the food, as well as the cooking temperature.
How often should I check the temperature of food while it’s cooking?
For larger cuts of meat or poultry, check the temperature periodically, starting about halfway through the estimated cooking time. This allows you to track the progress and make adjustments as needed. Checking too frequently can release heat and extend the cooking time, so avoid excessive probing.
For smaller items like steaks or chops, check the temperature more frequently as they approach the estimated cooking time. Since they cook faster, it’s important to monitor them closely to prevent overcooking. A few degrees can make a big difference in doneness, so precision is key.
Are there specific temperature guidelines for different types of food to ensure food safety?
Yes, different foods require specific internal temperatures to ensure that harmful bacteria are killed. For example, poultry should reach a minimum internal temperature of 165°F (74°C) to be considered safe. Ground meat, including beef, pork, and poultry, should also reach 160°F (71°C).
Beef, pork, lamb, and veal can be cooked to different levels of doneness, with varying safe internal temperatures. Steaks, chops, and roasts should reach a minimum of 145°F (63°C) followed by a three-minute rest time. Fish should be cooked to 145°F (63°C). Always consult reputable sources like the USDA for the most up-to-date food safety guidelines.
What are some common mistakes people make when using a food thermometer?
One common mistake is not inserting the thermometer probe correctly. It’s crucial to insert the probe into the thickest part of the food, avoiding bone and fat. Touching these can give inaccurate readings. Another mistake is not calibrating the thermometer regularly, which can lead to inaccurate temperature readings and potentially unsafe food.
Another mistake is relying solely on cooking time rather than checking the internal temperature. Cooking times are estimates and can vary depending on the oven, the size and shape of the food, and other factors. Always use a food thermometer to confirm the internal temperature and ensure food safety and optimal doneness. Finally, failing to account for carryover cooking can lead to overcooked results, especially with larger cuts of meat.
