Vodka tonic
A vodka tonic is an alcoholic drink made with varying proportions of vodka and tonic water. Vodka tonics are frequently garnished with a slice of lime or lemon. One commonly used recipe is one part vodka and one part tonic water in a tumbler, often a highball glass over ice, with a generous lime wedge squeezed into it. The drink is referenced in the lyrics of the song "Goodbye Yellow Brick Road" by Elton John.
