3 cups water
2 cups sugar
2 cups fresh lemon juice
2 cups fresh lime juice
1 cup tequila
1/2 cup triple sec
Make margarita base: Mix sugar and water in a saucepan and stir over medium heat until sugar dissolves. Bring to a boil, set aside and cool. Mix syrup, lemon and lime juices and chill until cold. Can be made one week ahead. When you're ready to serve, add the tequila and triple sec.
The first time we made this no one had a juicer. BIG mistake. Even WITH a juicer it's still a lot of trouble but ohhhh....it's a LOT of fun!
(And yes. I know that's not enough tequila. Handle it.)
