Vermouth

While sensible proportions are important to some and brand names of gin and vermouth essential to others, the real secret to a fine martini is stirring thoroughly but quickly to prevent the ice cubes from diluting the drink. It must also be served very cold and straight up.

Keep the glasses and a pitcher of the vodka in the freezer (for at least six hours before the party) so that you can provide instant gratification to each arriving guest. A medicine dropper is a great vermouth dispenser.
