I Am a Rock (Candy)

Rock candy has existed for a long time, at least 200 years.  However, rock candy as we know it (sugar crystals on a string or stick) seems to have first appeared in the late 1800s.  At that time, it was made with whisky and sold as a cough remedy.  The confection made its first appearance in the very early 1900s.  I will get my sources and update this posting later.
