The primary ingredient in a margarita is tequila. This classic cocktail typically consists of tequila, lime juice, and orange liqueur, such as triple sec or Cointreau. The drink is often served with a salted rim and can be garnished with a lime wedge. Tequila, made from the blue agave plant primarily in Mexico, lends its distinct flavor to the margarita, making it a popular choice in bars and restaurants. Variations of margaritas exist, including frozen and flavored versions, but the standard mixture remains a favorite among cocktail enthusiasts.
