Margarita

The margarita is a cocktail consisting of tequila, triple sec (such as Cointreau) and lime or lemon juice, often served with salt on the rim of the glass. It is the most common tequila-based cocktail in the United States.[citation needed][note 1] The drink is served shaken with ice (on the rocks), blended with ice (frozen margarita), or without ice (straight up). Although it has become acceptable to serve a margarita in a wide variety of glass types, ranging from martini and wine glasses to pint glasses and even large schooners, the drink is traditionally served in the eponymous margarita glass, a stepped-diameter variant of a cocktail glass or champagne coupe somewhat resembling an inverted sombrero.

Preparation

Rub the rim of the glass with the lime slice to make the salt stick to it. Shake the other ingredients with ice, then carefully pour into the glass (taking care not to dislodge any salt). Garnish and serve over ice.
