To check the accuracy of an instant-read meat thermometer, insert the metal stem into a pot of boiling water. Water boils at 212°F at sea level—that’s what should register on your thermometer. If the heat registers higher or lower, adjust the temperature using the lock nut on the back of the thermometer dial.
