National Brandy Alexander Day is observed worldwide every January 31. This day celebrates the Brandy Alexander cocktail, which gained popularity in 1922 during the wedding of Princess Mary and Viscount Lascelles in London. The cocktail is a variation of the original Alexander, which was made with gin. To prepare a Brandy Alexander, one combines 1.5 oz of brandy, 1 oz of dark crème de cacao, and 1 oz of half-and-half, shaking the mixture with ice and straining it into a martini glass, garnished with grated nutmeg. Additionally, the Brandy Alexander can be transformed into a dessert by adding a scoop of vanilla or chocolate ice cream, served in a wine goblet or any preferred glass. This day encourages people to enjoy this classic cocktail and its variations.
