Pink GinPink Gin was a fashionable cocktail in Britain in the mid-20th century, consisting of gin, a little water, and a dash of 'pink' (Angostura bitters, a dark red extract of gentian and spices, known from the 1820s at Angostura in Venezuela but now made in Trinidad).
Splash a tall glass with three or four dashes of Angostura Bitters. Move the glass around to coat the sides with bitters. Pour off excess. Pour a couple measures of gin in the glass and serve.
