Rock candy or sugar candy, [1] 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 [ 2 ] or navat .
These crystals were formed into a large solid cone for transport and sale. This solid sugar cone had to be broken into usable chunks using a sugar nips device. People began to notice that tiny bursts of light were visible as sugar was "nipped" in low light, an established example of triboluminescence. [6]
Sugar glass is made by dissolving sugar in water and heating it to at least the "hard crack" stage (approx. 150 °C / 300 °F) in the candy making process.Glucose or corn syrup is used to prevent the sugar from recrystallizing and becoming opaque, by disrupting the orderly arrangement of the molecules.
Sugar crystals are formed either due to agitation or the addition of crystal seeds in the form of powdered sugar or crushed fondant candy. The texture depends on the number and size of sugar crystals, the fat content, and the dispersion of milk solids. Nougats and marshmallows Nougats and marshmallows are confectionery foams, full of air. [8]
The sugar syrup is concentrated by boiling and then cooled and seeded with sugar crystals, causing the sugar to crystallize out. The liquor is spun off in a centrifuge and the white crystals are dried in hot air and ready to be packaged or used. The surplus liquor is made into refiners' molasses. [97]
