The art of the cocktail is indisputably non-Japanese. The word itself is old American slang for a pick-me-up, referring in modern parlance to any mixed drink containing liquor and at least one other ingredient. Even if you aren't a drinker, chances are you can name quite a few: the martini, the Manhattan, the gin and tonic. They're more than just libations, they're part of the Western vocabulary for relaxation.
