No one knows who invented the margarita. Its origins are as mysterious as the pyramids, but with more hangovers. Margaritas are pretty ubiquitous, and you can get them from some horrible frozen margarita machine, one of my pet hates!!!!!! But the real deal is so much better. Stop buying that horrible day-glo green mix and go back to the basics:
30mls fresh lime juice
Combine the ingredients in a mixing glass with ice. Shake well and strain into a chilled cocktail glass with a salted rim. Salting the rim: Rim the edges of the cocktail glass by rubbing a lime piece on the outside rim of the glass, then dipping the outside rim into a saucer of course salt.
