What is a necessary step in correctly using a thermometer?

Calibrating and sanitizing a thermometer are essential steps to ensure its accuracy and hygiene during food preparation. Calibration is necessary because it ensures that the thermometer provides the correct temperature readings, which is vital for food safety. Inaccurate readings can lead to improper cooking temperatures, risking foodborne illnesses. Sanitizing the thermometer is equally important as it prevents cross-contamination between different food items, maintaining a safe cooking environment. Together, these practices help ensure that food is prepared safely and at the correct temperatures. This thoroughness is crucial in any culinary setting where food safety standards are paramount.
