Hot. Buttered. Rum. Is there anything sexier than a glass of melted butter mixed with warm golden spirits? No, we think not. Americans have been whipping up a spiced butter batter and dousing it with rum and hot water since before they were Americans. This fancified version, created at Boston cocktail bar The Hawthorne, brings the winter warmer to its full velvety potential. With the crucial addition of ice cream and black tea, this variant closes the disappointing gap between expectation (decadent) and reality (greasy, watery) that often taints the hot buttered rum experience.
