It's another Tequila Sunrise
Starin' slowly 'cross the sky

With these words begins the song by the Eagles, released in 1973 and immediately becoming such a hit that it is believed to have somehow helped popularise the Tequila Sunrise.
This evocative cocktail, with its bright colours and warm ingredients that make you think of the sun, was born with a rather different recipe.

The original Tequila Sunrise was invented in the late 1930s and early 1940s by Gene Suilt, a bartender at the Arizona Biltimore Hotel, who mixed together tequila, lime juice, crème de cassis and soda. The definitive and later codified by the IBA version of the long drink, based on tequila, orange juice and grenadine, was allegedly created in the early 1970s by Bobby Lazoff and Billy Rice, of the Trident Bar & Restaurant in Sausalito, California.
The fame of the Tequila Sunrise, as well as the Eagles' song of the same name, is also due to the famous 1988 film starring Michelle Pfeiffer and Mel Gibson, which was released in Italy as Tequila connection, but whose original title is precisely Tequila sunrise.

A note of colour: despite being tequila-based, this cocktail is not as popular - as in the US - in Mexico, where it is apparently mostly ordered by tourists.
