Candy thermometer

Candy thermometer is a type of kitchen thermometer used to measure the temperature of sugar solutions in the process of candy making. Unlike other types of thermometers, candy thermometers can withstand high temperatures and provide precise readings that are crucial in candy making.

History

The candy thermometer was invented in the late 19th century, during a time when the science of confectionery was becoming more precise and measurements more critical. The exact inventor is unknown, but the device quickly became a staple in the kitchens of professional and amateur candy makers alike.

Design and Use

Candy thermometers are typically made of glass and contain a liquid such as mercury or colored alcohol that rises and falls with temperature changes. The thermometer is marked with different stages of sugar cooking, such as "soft ball", "hard ball", "soft crack", and "hard crack". These stages correspond to specific temperature ranges that indicate the concentration of sugar in the solution and the resulting texture of the candy once it cools.

To use a candy thermometer, it is clipped to the side of the cooking pot, with the bulb submerged in the sugar solution but not touching the bottom of the pot. As the solution heats, the liquid in the thermometer rises. The candy maker watches the thermometer and stops the cooking process when the desired temperature is reached.

Importance in Candy Making

The use of a candy thermometer is crucial in candy making because the temperature of the sugar solution determines the texture of the candy. For example, a lower temperature results in a softer candy, while a higher temperature results in a harder candy. Without a candy thermometer, it would be difficult to achieve the desired consistency.

Types of Candy Thermometers

There are several types of candy thermometers available, including traditional glass thermometers, digital thermometers, and laser thermometers. Each type has its own advantages and disadvantages, but all are capable of providing the accurate temperature readings needed in candy making.
