A banshee, in Irish folklore, was a female spirit who wailed when someone was about to die (hence the phrase “screaming like a banshee.”) We don’t know how this creamy, gentle cocktail came to be named after an omen of the underworld, but who cares? It’s creamy and sweet and tastes like bananas!
A cheap, clear liqueur like 99 Bananas will be too acrid for a drink with so few ingredients. If your local liquor store laughs in your face when you ask for high-quality banana liqueur (true story!), consider making your own – there are lots of great DIY banana liqueur recipes out there (we like the one from Serious Eats).
Shake with ice and strain into a cocktail glass, coupé, or other small, dainty glass. It’s even good over ice in a short glass, but you may want to decrease the cream (or milk), to account for the extra water in the drink.
