Horehound candy has a sweet, mildly bitter flavor that combines elements of mint and black licorice. Homemade horehound candy is made from a mixture of sugar, cream of tartar and an infusion of boiled horehound leaves.
Commercially manufactured horehound candy may be made with horehound extracts and additives, such as corn syrup and coloring. To retain the distinctive flavor without the excess sugar, horehound infusions can also be sweetened with honey or stevia and drunk as tea. Horehound (Marrubium vulgare) is a perennial European herb used to treat colds and digestive ailments such as intestinal parasites. Considered a weed in some parts of the United States, horehound has an equally distinctive yet very unpleasant odor, comparable to that of a skunk.
