You and my Grandfather would have gotten along just fine. He taught me how to make a properly DRY Martini....
Pour a generous tumbler of Gin. Garnish with an olive, or a twist of lemon, depending on your mood. Then, take a bottle of Vermouth and set it on a shelf. Look at the bottle of Vermouth, while drinking the Gin.
THAT'S a dry martini. :-)
Personally, I like what a bit of dry vermouth does to the gin, and that is after all, a martini. Otherwise, it's iced gin, and if you like that, no problem, but it ain't a martini.
And just for completeness sake, some classicists insist that without a dash of orange bitters it's not a real martini.
