The first Cinco de Mayo celebrations didn’t include
margaritas, because they weren’t invented until the 1940s. By the 1970s, the margarita surpassed the martini as the most popular American cocktail.
This is the first frozen margarita machine, invented at a restaurant owned by Mariano Martinez. When blenders couldn’t keep up with the high demand for margs, he found inspiration in the 7-Eleven Slurpee machine. The original retired when
Martinez’
restaurant moved 34 years later, and now it’s in our National Museum of American History.
