The History of the Frozen Margarita Begins in Dallas

A look at how one invention changed the margarita forever.

Posted on Jul 24, 2017

Not all frozen margaritas are created equal. In fact, whenever a bartender serves a frozen margarita around the world, its origins can be traced back to Dallas, Texas.

This story begins with a high school dropout who had dreams of opening his own business. With $500 in hand and a small business loan, Mariano Martinez opened Mariano's Hacienda restaurant in East Dallas. While the smell and sizzle of grilled fajitas and the fire-roasted salsa kept hungry guests coming back for more, it was the margaritas that brought them back for seconds.

Guests raved about Mariano's margaritas except for one very important detail: the consistency. His bartenders simply couldn't keep up with the growing demand that left some perfect, while others were melted down. Martinez knew he had to come up with a solution.

His a-ha moment came to him during a morning visit to 7-Eleven for a cup of coffee. Low and behold, it was the Slurpee machine that sparked the idea that will live on forever! Martinez and a friend, Frank Adams, tinkered with an old soft-serve ice cream machine until it resulted in a frozen margarita that was served to perfection with every pour. And just like that, the world's first frozen margarita machine was born!

Today, the original machine can be found at the Smithsonian National Museum of American History.
