How to Make It
Put marmalade, honey, lemon juice in a large pot with water and heat over medium heat, stirring every now and then, until marmalade is melted. Stir in whisky and orange juice. Pour into decanters or pitchers and serve with a stirring spoon on the side, since the marmalade sinks. Set out with glasses, ice, and fresh orange slices or delicate dried orange slices (find at gourmet stores and Trader Joe’s) to float in the glass.
Make ahead: Chilled, up to 1 week; up to 3 months, frozen (if you use a glass jar, fill to 2 inches below lid so it won’t explode).
