What is the primary flavor in a frozen margarita?

The primary flavor in a frozen margarita is lime. This classic cocktail features lime juice as its foundational flavor component, which provides the signature tartness that balances the sweetness of other ingredients such as orange liqueur and the smoothness of tequila. The refreshing and zesty profile of lime is what makes the margarita a popular choice, especially when served frozen. While other fruit flavors can be added to create variations, the traditional margarita is unmistakably anchored by the sharp, citrusy taste of lime, making it the essential characteristic of the drink.
