A classic Dry Martini without bitters and garnished with cocktail onions in place of an olive or a twist. On those two distinctions, all are agreed. However...
Seemingly a great 5:1 cocktail. Actual recipe would read a lot better as 60ml gin and 12ml vermouth. 62.5ml is a little too precise for most bar measures. And, for us Yanks, goodness knows, nobody has ever used a 12th of an ounce as a measure of anything.
