Alexander's Sister Cocktail

Pro tips

• Shake hard with fresh ice for at least 10 seconds to properly emulsify the cream and chill the drink below 40°F.
• Use light cream, not milk—it provides the silky mouthfeel without being too heavy; avoid whipped cream.
• Chill your coupe glass beforehand; the creamy texture shows best in a cold glass.
• Pour crème de menthe slowly and measure precisely—too much mint will overpower the gin's botanicals.

Substitutions

• Mr. Boston Dry Gin → any London Dry gin (Beefeater, Tanqueray, Gordon's)
• Light cream → half-and-half (thinner texture) or heavy cream (richer)
• Green crème de menthe → white crème de menthe (lighter color, identical mint flavor)

What's the difference between Alexander's Sister and an Alexander cocktail?

An Alexander uses crème de cacao (chocolate liqueur) instead of crème de menthe, making it sweeter and less herbal. Alexander's Sister swaps in green crème de menthe for a mint-forward profile.

Can I use half-and-half instead of light cream?

Yes. Half-and-half will make the drink slightly thinner; heavy cream will make it richer. Light cream is the traditional choice for balanced texture.

Should this drink be shaken or stirred?

Shake vigorously with ice for 10–15 seconds to chill, emulsify the cream, and create a silky texture. Strain into a coupe or cocktail glass.

What gin works best for this cocktail?

Dry, London Dry–style gins (like Mr. Boston) work well because their botanical profile balances the sweetness of crème de menthe without overpowering it.

Is this cocktail suitable for non-dairy diets?

No, cream is essential to the recipe's texture and taste. Coconut cream or oat cream may substitute, though the flavor profile will shift.
