Agree with John Hinojos - it's a great "evening sipper cocktail", rather more serious and subtle than a Cosmopolitan what with it's gin base and omission of orange/lemon flavours. Using Giffard Tayberry liqueur and the not-too-sweet Eager Cranberry, the drink is tangy and refreshingly sour. Depending on brands used, some may like a few dashes of sugar syrup. Clean, sensible flavours.
