In a small saucepan, mix together the raspberry simple syrup ingredients (1/2 cup of raspberries, water, and sugar). Bring to a gentle simmer. Simmer for roughly 10 minutes, stirring frequently, until mixture has thickened a bit.
Let cool for 5 minutes and then puree in a blender or food processor. If desired, you can strain the mixture to remove the berry seeds.
To make the mojitos: in 2 glasses, pour 1/2 cup of the raspberry puree. Place 8 mint leaves and 2 lime wedges into each glass and muddle to release the flavors. Top each glass off with ice and fill to the top with the club soda.
Garnish with extra raspberries and mint and ENJOY!
