Chocolate World Sugar Thermometer

Chocolate World Thermometer to determine the temperature of sugar. A sugar thermometer, also known as a candy thermometer or jam thermometer, is a cooking thermometer used to measure the temperature and therefore the stage of a cooking sugar solution. A sugar thermometer is similar to a meat thermometer but can read higher temperatures, usually 400 °F/200 °C or more. Sugar thermometers can also be used to measure hot oil for deep frying since it can reach higher temperatures than a normal thermometer.

Candy thermometers have been used by the general public since World War I, although they had been available to professional candymakers earlier than that and were mentioned as early as 1896 in Fannie Farmer's Boston Cooking-School Cook Book. Before, cooks had to use the "water test," i.e., placing a portion of syrup into cold water to judge its temperature.
