A simple, 3-ingredient holiday drink made with softened butter, brown sugar, and dark rum. This recipe creates a velvety, emulsified beverage that offers deep caramelized warmth and comfort.
Butter must be softened, not melted, to ensure proper emulsion. Water must be boiling to dissolve sugar and melt butter instantly. Whisking vigorously is crucial to prevent the butter from separating. The butter-sugar paste can be made in advance and stored in the fridge for up to two weeks.
