Reed candy, also known as reed canary grass candy, is a type of candy made from the roots of the reed canary grass plant. The plant is common to Europe and Asia and is sometimes used in traditional medicine. The candy is made by boiling the roots in sugar syrup, and then crystallizing the syrup into candy form. Reed candy is known for its sweet taste and crunchy texture. It was popular during the Victorian era and was often used as a cough remedy due to its purported medicinal properties. Although it is no longer widely consumed today, reed candy can still be found in some specialty shops and online.
