The Rosita is a drink I first encountered in August 1999 issue of GQ Magazine. It was in an article written by Terry Sullivan, where he was providing a cautionary tale about drinking too much tequila. The Rosita didn't figure in his tale, but for whatever reason he chose to end the article with this delightful little drink. After trying it, I decided it was probably my favorite tequila cocktail, and one that rarely appeared to be listed in cocktail books of the day.
