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 or stick. Heating the water before adding the sugar allows more sugar to dissolve thus produces larger crystals. Crystals form after 6–7 days. Food coloring may be added to the mixture to produce colored candy.
Famous quotes by rock candy:
“I’m headed for a land that’s far away
Beside the crystal fountains.
So come with me, we’ll go and see
The Big Rock Candy Mountains.”
—Unknown. The Big Rock Candy Mountains (l. 5–8)
