One 1-liter bottle of tequila
2 cups Cointreau
2 cups unsweetened pomegranate juice
1 cup fresh lime juice
In a large glass pitcher, combine the tequila, Cointreau, pomegranate juice and lime juice. Fill a cocktail shaker with ice, pour in 1 cup of the margarita mix and shake well. Strain into a cocktail glass and serve. Repeat with the remaining mix.
