When deep-frying or making candies and jellies, the temperature of the liquid must be closely monitored using a thermometer. These thermometers must withstand much higher temperatures than oven thermometers. They are usually much larger and come with a hook to attach to the side of the pot to keep them from touching the hot metal. Temperatures usually range from 100 to 400 degrees F.
