Long known as a soothing syrup and tonic sweet, horehound candy used to be on sale in grocers’ shops in Victorian times, and was a favorite with children: a healthful sweet. Into two pounds of brown or lump white sugar (latter is most typical for horehound candy, though less healthful), stir four tablespoons of horehound infusion (the strained liquid obtained from boiling a handful or the dried herb in one and a half cups of water). Mix in two teaspoons of thick honey. Boil together for a half-hour, or until a portion taken hardens when dropped into cold water. Then pour onto a cold marble slab (preferably) or into shallow tin molds dusted with icing sugar.
