crystalised sugar candy
Confection composed of relatively large sugar crystals

Rock candy or sugar candy, also called rock sugar, or crystal sugar, is a type of confection composed of relatively large sugar crystals. In some parts of the world, local variations are called Misri, nabat or navat. 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 six to seven days. Food coloring may be added to the mixture to produce colored candy.

Etymologically, "sugar candy" derives from late 13th century English (in reference to "crystallized sugar"), from Old French çucre candi (meaning "sugar candy"), and ultimately from Arabic qandi, from Persian qand ("cane sugar"), probably from Sanskrit khanda ("piece of sugar)", The sense gradually broadened (especially in the United States) to mean by the late 19th century "any confection having sugar as its basis". In Britain, these are sweets, and "candy" tends to be restricted to sweets made only from boiled sugar and striped in bright colors. The modern American term "rock candy" (referring to brittle large natural sugar crystals) should not be confused with the British term rock (referring to an amorphous and opaque boiled sugar product, initially hard but then chewy at mouth temperature).

Islamic writers in the first half of the 9th century described the production of candy sugar, where crystals were grown through cooling supersaturated sugar solutions. One of the famed makers of rock candy in the Muslim east is Hafiz Mustafa in 1864 in Istanbul founded during the reign of Sultan Abdulaziz. According to the production process, rock sugar is divided into two types: single crystal rock sugar and polycrystalline rock sugar.

Rock and rye is a term used both for alcoholic liqueurs and cocktails using rye whiskey and rock candy, as well as for non alcoholic beverages made in imitation thereof, such as the "Rock & Rye" flavor of soda pop made by Faygo.
