2 ounces gin
5 ounces tonic water
1 lime wedge
Pour the gin and tonic water into a highball glass that has been filled with ice cubes. Stir well and garnish with the lime wedge.
My favorite gin to use in the United States is Tanqueray No. Ten. Another good option for gin is Bombay Sapphire. Bombay Sapphire may not be quite as good as the Tanqueray No. Ten but it is still quite good and here in Switzerland I have taken to using it as Tanqueray No. Ten is much harder to find without a trip to London or at least a higher end liquor store.
