Hot Buttered Rum is a classic winter cocktail. It’s sweet, slightly spicy (thanks to nutmeg and allspice) and delightfully boozy. I had no idea how many iterations there were until I researched recipes. The preparation is much the same; you cream butter and sugar together, add cream or melted vanilla ice cream, and winter spices like nutmeg, cinnamon and allspice. When making a cocktail, you add two tablespoons mix to a heatsafe mug and add a shot of rum and top with hot water.
