Step 1

Place 6 martini glasses in the freezer and chill until frosted, at least 1 hour.

Step 2

Combine gin, pomegranate juice, lime juice and simple syrup in a large pitcher. Fill a cocktail shaker halfway with ice and add the drink mixture until the shaker is three-quarters full. Cover and shake for 15 seconds. Strain the mixture into the frozen martini glasses. Repeat with the remaining drink mixture, adding more ice to the shaker as necessary. Garnish with pomegranate arils and lime slices, if desired.
