1. Muddle mint leaves and granulated sugar in your pitcher.
2. Add the simple syrup, fresh lime juice, rum and club soda to your pitcher and gently stir.
3. Add ice to glasses, and garnish with lime slices and fresh mint.
4. Pour mojitos over the ice and serve.

Pro-tip: if you're planning to store your Mojito Party Punch, wait to add the club soda until you're ready to serve. Cover the pitcher and refrigerate for up to 3 days.
