The primary ingredient in a traditional margarita is **tequila**. This iconic cocktail has its roots in Mexico and is typically made by blending or shaking tequila with lime juice and orange liqueur, often served in a glass with a salted rim. Tequila, made from the blue agave plant, is known for its distinct flavor that varies by production process and aging. Margaritas can be enjoyed on the rocks or blended with ice for a frozen version, making them a versatile and refreshing choice. Popular variations might include flavored margaritas, such as strawberry or mango.
