Saketini
Saketini is the name of a cocktail that uses sake and other ingredients such as simple syrups, distilled spirits, liqueurs, juices and garnishes. The name saketini comes from the recent and popular usage of the suffix "-tini", derived from the name for the classic cocktail, the martini, to denote any alcoholic drink that is served chilled in a cocktail glass.
