The Margarita is arguably the most famous tequila cocktail in the world. Its perfect balance of sweet, sour, and salty makes it irresistible. The origin of the drink is shrouded in myth, but most stories place its creation in the 1930s or 1940s in Mexico or along the US border. A classic Margarita is not a frozen slushy but an elegant, shaken cocktail served "straight up" (without ice) in a chilled glass with its characteristic salt rim. It is the ultimate proof of how great tequila can taste in a mixed drink.
