A margarita is a cocktail consisting of tequila, orange liqueur, and lime juice often served with salt on the rim of the glass. 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 cocktail 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.
According to cocktail historian David Wondrich, the margarita is merely a popular Mexican and American drink, the Daisy ("margarita" is Spanish for "daisy"), remade with tequila instead of brandy, which became popular during Prohibition as people drifted over the border for alcohol. There is an account from 1936 of Iowa newspaper editor James Graham finding such a cocktail in Tijuana, years before any of the other margarita "creation myths".
