In a small pan over high heat add equal parts sugar and water. I usually do a 1/2 cup sugar and 1/2 cup water. Bring it to a simmer, stirring so that all of the sugar dissolves. Once the sugar is dissolved turn it off and let it come to room temperature. Voila! Simple syrup.
In a shaker muddle together the fresh lime, blueberries, and mint leaves until all of the juice is released from the lime
To the shaker add the ice, simple syrup, and rum. Add the lid to the shaker and shake vigorously
Pour into a glass and top it with club soda
That’s it! A refreshing cocktail perfect for Summer… or anytime of the year. Cheers!
