This year, I'll make something like horehound cough drops:
boil a quarter of a cup of the leaves in 2 cups of water for 10 minutes;
discard the leaves. Add twice as much honey as the remaining liquid and
stir the mixture smooth. Then blend 2 cups of sugar with 1/8 teaspoon of
cream of tartar in a saucepan, and add the honey-horehound mixture. Stir
over medium heat until the sugar melts. Then lower the flame and continue
stirring until a dollop of the candy forms a hard ball when dropped into
cold water. At that point you can pour the syrup into a buttered baking
dish and cut it into small squares as the candy begins to harden. Finally,
roll the pieces in powdered and then granulated sugar and store them in
airtight containers. Source unknown.
