What tool is used to measure the core temperature of food accurately?

The correct choice for measuring the core temperature of food accurately is a temperature probe. Temperature probes are specifically designed to penetrate food and give a precise reading of the internal temperature, which is essential for ensuring that food is cooked safely and to the desired doneness. They are often equipped with a digital display for easy reading and can provide fast results, which is particularly important in food safety practices.

While food thermometers and cooking thermometers are generally similar in that they also measure temperature, the term "temperature probe" emphasizes the ability to insert the device into the thickest part of the food, allowing for a more accurate core temperature reading. Measuring cups, on the other hand, are not suitable for temperature measurement, as they are designed for volume measurement.
