A cooking thermometer is a kitchen tool used to measure the internal temperature of food. It helps ensure that meats, poultry, and baked goods are cooked to safe temperatures, preventing foodborne illnesses. There are various types, including digital, dial, and infrared thermometers, each offering different features for accuracy and ease of use. Using a cooking thermometer is simple. Insert the probe into the thickest part of the food, avoiding bones or fat, and wait for the reading to stabilize. This tool is essential for achieving perfect results in dishes like roast chicken or chocolate cake, ensuring they are both safe and delicious.
