The Classic Martini. Don't argue with me.

The “Don’t Argue with Me” Classic Martini

This is a Classic Martini. You disagree? Then write your own damn book.

4 parts high quality gin—we like Hendricks and Bombay Sapphire.  Tanqueray  is perfectly good, too. (If you want to use good vodka, fine; just don’t call it a Classic Martini.)
1 part dry vermouth
Fill shaker with ice. Pour liquors in. Just let it sit on the counter to chill—no need to shake. Stir just once, put the lid on, and strain your Classic Martini into the proper glass. Add an olive or a lemon twist; a cocktail onion turns it into a Gibson.
