"… while visions of sugarplums danced in their heads." The famous sugar plums spoken about in Clement Clark Moore's beloved poem, "'Twas the Night Before Christmas" were actually sugar-coated coriander. Later the recipe changed and included other spices and dried fruit. This recipe is based on the confection we know today. Sugar plums tend to absorb the powdered sugar, so redust just before eating, if you like.
