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, allowing cooks to ensure that meats, baked goods, and other dishes are cooked to safe temperatures. This helps prevent foodborne illnesses and ensures optimal cooking results. There are two main types of probe thermometers: instant-read and leave-in. An instant-read thermometer provides a quick temperature reading when inserted into food, while a leave-in thermometer remains in the food during cooking, allowing for continuous monitoring. Both types are essential for precise cooking.
