Pomegranite Martini

In a small saucepan combine 1/4 cup water and 1/4 cup sugar; bring to a simmer, then remove from heat and let cool. In a large pitcher combine the sugar syrup with 3/4 cup vodka, 1/2 cup pomegranite juice, 1/3 cup fresh lime juice, and 1/4 cup cointreau. Add 2 cups ice and stir until well chilled. Strain into chilled martini glasses; garnish with a lime slice. Serves 4
