A probe thermometer is a kitchen tool used to measure the internal temperature of food. It typically consists of a metal probe connected to a digital display or dial. This device helps ensure that meats, poultry, and other dishes are cooked to safe temperatures, preventing foodborne illnesses. To use a probe thermometer, simply insert the metal probe into the thickest part of the food, avoiding bones or fat. The reading on the display will indicate the temperature, allowing cooks to achieve the desired doneness. This tool is essential for both home cooks and professional chefs in ensuring food safety and quality.
