Put the lime wedges in a Mojito glass (or if your muddler does not fit the Mojito glass like mine, do this in a separate bowl). Crush the lime to release its juice.
Add the blueberry lavender syrup and the simple syrup and mix well.
Fill the glass (or transfer to a Mojito glass and then fill it) with the ice cubes.
Add the rum and fill the glass with cold soda water. Mix.
Serve immediately and enjoy!
Recipe Notes
Simple syrup is made by melting the same amount of water and sugar over the fire. Let it cool down completely before adding it to your drinks.
