Rock candy (also called rock sugar) is a type of confection composed of relatively large sugar crystals. This candy is formed by allowing a supersaturated solution of sugar and water to crystallize onto a surface suitable for crystal nucleation, such as a string, stick, or plain granulated sugar. Heating the water before adding the sugar allows more sugar to dissolve thus producing larger crystals. Crystals form after 6–7 days. Food coloring may be added to the mixture to produce colored candy.
Candied sugar has its origins in Iran. Islamic writers in the first half of the 9th century described the production of candy sugar, where crystals were grown as a result of cooling supersaturated sugar solutions. In order to accelerate crystallization, confectioners later learned to immerse small twigs in the solution for the crystals to grow on. The sugar solution was colored with cochineal and indigo and scented with ambergris or flower essence.
The name comes from the medieval era, and in turn lends its name to a British candy called rock.The Founder of Rock Candy is unknown.
Rock candy is often dissolved in tea. It is an important part of the tea culture of East Frisia, where a lump of rock sugar is placed at the bottom of the cup. Rock candy consumed with tea is also the most common and popular way of drinking tea in Iran. In Iran it is called nabat, and the most popular nabat is saffron.
In China, it is used to sweeten Chrysanthemum tea as well as Cantonese dessert soups and the liquor baijiu. In some Chinese provinces, it is used as a part of traditional Chinese medicine. It is a common ingredient in Chinese cooking, and many households have rock candy available to marinate meats and add to stir fry. Rock candy is also regarded as having medicinal properties and is used to prepare food such as yao shan. In less modern times, rock sugar was a luxury only for the wealthy.
