"The Nite Kappa is a vegetal, yet fruit-forward cocktail inspired by a relatively obscure classic called the Royal Smile, which was first printed in The Savoy Cocktail Book by Harry Craddock in 1930 and consists of gin, apple brandy, lemon, and grenadine," says Rule of Thirds partner Brian Evans. "Our take is a split base of Irish gin and aquavit, for an herbaceous and spiced backbone, along with a grenadine-like cherry syrup. Fresh cucumber juice is added to enhance the balance from being too fruity, while also giving nod to the cocktail name, as the "Kappa" is an amphibious and rather violent Japanese mythical creature that feasts on cucumbers."
