How Texas Invented the Frozen Margarita

The frozen margarita, a drink loved by Texans throughout the state,  is a staple in modern Tex-Mex.  However, did you know the frozen margarita as we know it today has its origins in Texas?

Although the classic margarita has several unclear origin stories, the concept of transforming it into a slushy treat, the frozen margarita, can be credited to Dallas restaurateur Mariano Martinez, who introduced it in 1971.

A Simple Yet Innovative Solution to A Common Problem

Martinez owned a restaurant called Mariano’s Mexican Cuisine in East Dallas. His bartenders often struggled to maintain consistency, flavor, and coldness when preparing margaritas by hand, particularly during busy service hours.

Customers occasionally complained that the drinks "weren't cold enough" or that each margarita had a different taste.

Martinez recognized a potential solution in an unexpected place: the Slurpee machine at a 7-Eleven.

He realized that if he could adapt a machine designed for making semi-frozen beverages, he might address both the issues of volume and quality.

Mariano Martinez repurposed a soft-serve ice cream machine to serve margarita slush.

Who would've ever thought a simple 7-Eleven run would inspire such a brilliant idea?

The Day That Changed Everything

On May 11, 1971, he pulled the lever for the first time, dispensing frozen margaritas from the machine.

This moment not only transformed his restaurant but also introduced a new way to enjoy margaritas that would spread across the country, becoming a defining aspect of Tex-Mex and cocktail culture.
