Frozen margarita — Dallas, the United States
A frozen margarita is a margarita served as a slushy: tequila, lime juice and orange liqueur, with sugar, transformed into a cold, creamy mix. It’s the drink of many nights at Tex‑Mex restaurants, served in a wide‑rimmed glass with the rim dipped in salt.
A margarita blended in a blender with ice already existed, but it varied from glass to glass and took time to be ready. On May 11, 1971, Mariano Martinez, a young man from Dallas who had just opened his restaurant, adapted a soft‑serve ice cream machine to make frozen margaritas always the same, using his father’s recipe. The idea was copied by bars and restaurants across the country, and Martinez never patented it.
The original machine was donated to the Smithsonian’s National Museum of American History in Washington, where it is part of the exhibition on changes in the American table. For the museum, the machine also tells the story of Tex‑Mex cuisine, which spread across the United States from the 1970s onward.
In Dallas and the rest of Texas, the frozen margarita accompanies Tex‑Mex dishes and also appears in fruit flavors in addition to lime. It is an alcoholic drink: enjoy in moderation.
