a Martini, by Laurea, in 6.7 seconds.
We’re always a little disappointed to see a martini glass with anything other than a martini inside it. Think about it: the Fastest Possible Martini is the fastest possible identifiable cocktail, as long as you assume that there is only one permissible use of a martini glass (and you should).
We won’t take sides in the great “gin versus vodka” debate, other than to point out Jim Coudal's perfect description of the perfect martini. Fortunately for us, when working with a single pen, a blank card, and as little time as possible, all alcohols are clear. Other than that, there is only an olive here, small and perfect, speared with a toothpick; if you have identified it as a maraschino cherry, you have made a mistake, as–again–only a martini can be served in a martini glass, and no martini is served with a cherry.
To that end, does our tautological argument about the quintessential martini-ness of the martini glass hold water? [ed: No.] Could the Fastest Possible Martini be the simple elevated wedge profile of the glass itself? Understand this, reader: We hold ourselves to a higher standard; we are not simply depicting, but instructing. A martini glass holds a martini–there must be a martini within it, and a martini is [either gin or vodka], [shaken or stirred], with only the distant memory of vermouth and an olive (or two). If you did not know this, now you know. You also know that it takes 6.7 seconds to draw it.
Perhaps it is a bit early to put this out there, but it’s always noon somewhere, and history requires that I mention it: This, thrice over, makes a killer lunch. Enjoy them slowly, and converse.
