Classic Martini...not "Shaken" or "Stirred"

From http://inthekitchenwithkath.com

Good quality Gin that has been in the freezer (I use Tanqueray)

Lemon

Cocktail onions, and/or olives

Extra dry Vermouth

Pour the gin into a martini glass. Cut a lemon twist from the lemon. Rub the rim of the glass with the lemon twist, and then drop it in the gin. Pour just a very few drops of Vermouth in. Garnish with cocktail onions and/or olives. Give it a quick stir to blend the Vermouth and gin. Serve.
