The Alexander's Sister swaps the Alexander's crème de cacao for green crème de menthe, shaken with cream and dusted with nutmeg. Cool peppermint leads over a soft, velvety body of gin and cream, finishing with a warm dusting of nutmeg — a dessert-style after-dinner sipper.
The Alexander's Sister appears in Harry Craddock's 1930 The Savoy Cocktail Book, listed alongside the Alexander Cocktail No. 1 and No. 2. It is the mint variation within the Alexander family, replacing the crème de cacao of the cream-and-gin Alexanders with crème de menthe, which gives it a herbal, green character in place of the chocolate note. Craddock's original is built in equal parts of gin, crème de menthe, and cream.
The Alexander's Sister is a creamy gin cocktail and a mint variation of the classic Alexander. It uses green crème de menthe in place of crème de cacao, shaken with London dry gin and cream, then finished with grated nutmeg.
Combine London dry gin, green crème de menthe, cream, a little sugar syrup, and egg white. Double shake — first with ice, then dry without ice — fine-strain into a chilled coupe, and dust with freshly grated nutmeg.
The original Alexander is gin, crème de cacao, and cream, shaken and strained. The Alexander's Sister keeps the gin and cream but swaps the cacao for green crème de menthe, while the Brandy Alexander uses brandy instead of gin.
An Alexander's Sister is served straight up in a chilled coupe glass. The chilled glass keeps the creamy, mint drink cold without ice diluting it, and the nutmeg garnish is dusted over the top.
It is shaken — specifically double shaken. The cream and egg white need hard shaking to emulsify and build a smooth foam, so the drink is shaken with ice, then dry shaken without ice before straining.
