The frozen margarita in Dallas is a blended mixture of tequila, triple sec, and lime juice served in a salt-rimmed glass from machines that run continuously in Tex-Mex restaurants. Dallas claims the invention of the machine-blended frozen margarita in 1971.

Dallas restaurateur Mariano Martinez claims to have invented the first frozen margarita machine in 1971 at his restaurant Mariano's, adapting a 7-Eleven Slurpee machine to dispense a pre-blended margarita. The machine is in the Smithsonian Institution's National Museum of American History in Washington D.C. The frozen margarita subsequently spread from Dallas to every Tex-Mex restaurant in the United States.
