To make a great margarita for a party, combine 1 1/2 ounces of tequila, an ounce of lime juice and 1/2 an ounce of Cointreau in a salt-rimmed glass full of crushed ice. Stir gently a few times until the drink is chilled, then serve immediately.
As of March 2015, this recipe is rated four and a half out of five stars, based on 154 ratings, according to Chow. There are several variations of this classic margarita recipe, including using triple sec instead of Cointreau; adding fruits such as strawberries, blackberries, mango or watermelon; and combining the ingredients in a blender to make a thick frozen beverage.
Who invented the first margarita is unclear, as more than one person claims to have created the cocktail. Carlos "Danny" Herrera claimed to make the drink for actress Marjorie King in 1938 because she was allergic to all alcohol except tequila. However, Dallas socialite Margarita Sames said she crafted the drink for friends at her home in Acapulco in 1948.
It gained notoriety when well-connected friend Tommy Wilson had the beverage put on all the bar menus in his hotel chain. The margarita continued to become popular when it was featured in the 1953 December issue of "Esquire" magazine as the Drink of the Month, and with the release of the song "Margaritaville" by Jimmy Buffet.
