What is the purpose of using a thermometer when cooking?

Using a thermometer when cooking serves a critical function in verifying the internal temperature for safety. This practice is essential because reaching the correct internal temperature is necessary to eliminate harmful bacteria and ensure that the food is safe to eat. Different types of foods require specific temperature thresholds to prevent foodborne illness, making the thermometer an invaluable tool in the kitchen.

While ensuring food cooks evenly, checking if food is ready to serve, and measuring cooking time are relevant aspects of cooking, they do not directly address the key safety concerns. Only by accurately measuring the internal temperature can a cook confirm that food has been cooked sufficiently to prevent health risks associated with undercooked items.
