A kitchen thermometer used for testing the temperature during the preparation of candy, syrups, jams, jellies and deep fat. It should register from 100° to 400°F. Choose a thermometer that is easy to handle in hot mixtures, such as one with a plastic handle. Many have adjustable hooks or clips so the thermometer can be attached to a pan. There are dual-purpose thermometers with readings both for candy and deep fat.
