Rock candy is pre¬ pared by immersing a string in a concentrated cane-sugar solution. The sugar is deposited slowly upon the string in crystals which in¬ crease in size as long as they are immersed in a sugar-containing solution. Rock candy is used for chemistry experiments when very pure sucrose is needed. Cream or texture candies may be coated with crystals by immersing them in a cold sugar solution. Two parts of sugar are dis¬ solved in one part of water, and the solution is concentrated to a boiling point of 225° F. If candies are allowed to stand in this solution 12 to 24 hours, a coat of crystals is formed over the outside. This improves the ap¬ pearance and the keeping quality of cream bonbons and gum drops. Large crystals are obtained by use of sucrose sirups of low concentration. The crystals are allowed to form slowly until the desired size is obtained. Cream candiesCream Candies present a special problem These temperatures have been calculated for places with boiling points of 212° F. Where the boil¬ ing point of water is less than 212°, decrease the above temperatures by the difference between 212° and the actual boiling point at that location. This same cor¬ rection should be made for the other temperatures in this chapter, if used where the boiling point of water is lower than 212° F. [37] in crystallization. In this group of candies crystals are wanted, but small crystals that cannot be felt separately on the tongue. To obtain small crystals one must make sure that they are formed rapidly. Cream candies are made from granulated sugar (sucrose). The sugar is dissolved in the liquid, water or milk. This breaks down its crystalline form. The sirup then is boiled until it reaches the soft-ball stage, indicated by a temperature of 237° F.
