When calibrating a thermometer, what temperature should it be set to using the slush method?

The slush method for calibrating a thermometer involves using a mixture of ice and water to create a freezing, slushy environment. This method is based on the fact that pure water freezes at 32°F (0°C), making it an ideal reference point for thermometer calibration. By immersing the thermometer in this slush until it stabilizes, you can ensure that it accurately reads this critical temperature. Proper calibration is essential in food safety to ensure accurate temperature measurements, which help prevent foodborne illnesses. Using the slush method allows food service professionals to verify that their thermometers are measuring temperatures correctly, particularly when checking for safe temperatures in food storage and cooking processes.
