Which thermometer is the most widely used to take the internal temperature of food?

The bimetallic thermometer is a widely used tool for measuring the internal temperature of food, especially in conventional kitchen settings. Its design features a metal probe that contains two different types of metal bonded together. When the probe is inserted into food, the temperature causes the metals to expand at different rates, which then moves a dial to indicate the temperature reading. This type of thermometer is particularly effective for larger, thicker foods where precise temperature measurement is vital to ensure safe cooking and serving temperatures.

While digital thermometers offer faster readings and are also popular in culinary settings, they can be less common for specific applications like checking the temperature of larger food items. Infrared thermometers, on the other hand, measure surface temperature without contact and are not suitable for determining the internal temperature of food, which is essential for safety and doneness. Thermocouples provide quick and accurate temperature readings as well, but they are typically used in more specialized environments. Therefore, the bimetallic thermometer remains a fundamental and commonly utilized tool in food preparation and safety practices.
