A margarita is a cocktail consisting of tequila, triple sec, and lime juice. Some margarita recipes include simple syrup as well and are often served with salt on the rim of the glass. Margaritas can be served either shaken with ice (on the rocks), without ice (straight up), or blended with ice (frozen margarita). Most bars serve margaritas in a stepped-diameter variant of a cocktail glass or champagne coupe called a margarita glass. The margarita is one of the world's most popular cocktails and the most popular tequila-based cocktail. Origin.
