Rock_candy

A partially eaten stick of yellow rock candy.

Rock candy crystallized in the form of cubes.

Rock candy (also called rock sugar) is a type of confectionery composed of relatively large sugar crystals. Homemade rock candy is commonly formed by allowing a supersaturated solution of sugar and water to crystallize onto a string or some other surface suitable for crystal nucleation. Heating the water before adding the sugar allows more sugar to dissolve and thus produces larger crystals. Crystals form after several days. Food coloring is often added to the mixture to produce colored candy.

Origins

Candied sugar has its origins in India and Persia. Arabic writers in the first half of the 9th century described the production of candy sugar. Crystals were grown as a result of cooling supersaturated sugar solutions. In order to accelerate crystallization, confectioners later learnt 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.[1]

Etymology

Originated mid 17th century (as a verb): the noun use is from late Middle English sugar-candy, from French "sucre candi" "crystallized sugar", from Arabic sukkar "sugar" plus ḳandī "candied", based on Sanskrit, khaṇḍa "fragment".

In cuisine
