:''"Rock sugar" redirects to here'' Rock candy (also called rock sugar) is a type of confectionery mineral 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. ==Origins== 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.〔Richardson, Tim. (2002) ''Sweets: A History of Candy''. Bloomsbury.
