Rock Candy is the product of the further refining by recrystallization of pure cane sugar. In fact, it is the purest form of sugar available because all impurities are excluded as the large crystals form. The crystal growth is based on the particular characteristics of sugar (sucrose) chemistry.
Rock Candy is made by a process of crystalization, the same process that produces quartz and diamonds in nature (with a different ingredient, of course). It is made by busting apart the sugar (sucrose) molecular crystal lattice and then allowing it to re-form in conditions that produce larger, purer crystals. A hot, saturated solution of cane sugar and water is poured into large tanks. Careful supervision of the cooling process produces the larger crystals which are then harvested as Rock Candy Strings, sticks, and loose crystals for packaging.
