Candy thermometer

(See candy making for a description of sugar stages.)

Candy thermometers have been used by the general public since World War I, although they had been available to professional candymakers earlier than that[1] and were mentioned as early as 1896 in Fannie Farmer's Boston Cooking-School Cook Book.

They may include a clip to attach the thermometer to the side of the saucepan.

Some thermometers have markers indicating which stage the sugar is at, and alarms that go off after a given temperature is reached.
