I have three basic recipes for Vodka martinis. All of these recipes require a chilled glass, dry french vermouth such as Noilly Prat and a fairly neutral russian vodka such as Moskovskaya. All are finished with a twist of lime.
Dry: Pour one measure of vermouth into a martini glass. Swish it around and pour it out. Then pour 5 measures of vodka into a completely different glass.
Very Dry: Pour 5 measures of vodka into a martini glass. Hold the vermouth bottle up and let the light pass through it and fall onto the martini glass.
Perfect: Pour 5 measures of vodka into a martini glass. Sip, slowly, while reminiscing about the taste of vermouth.
