Perfect Manhattan is an American cocktail made with a combination of rye whiskey, Angostura bitters, and equal parts sweet and dry vermouth. In order to prepare it, all ingredients are shaken with ice, then strained into a cocktail glass.
The cocktail is typically garnished with a cherry or a lemon twist, which should be added directly over the drink to release its essential oils. The word
perfect in the name of this drink refers to equal amounts of dry and sweet vermouth used in the preparation process, not to the quality of the cocktail.
