Divide and add the Rum and the Caster Sugar – give a light stir until the Caster Sugar has dissolved
Add 6 Mint Leaves as well as 1 quartered Lime (see *** note below) to each glass
Top up with Soda Water, gently stir and serve immediately
Notes
Before adding the Mint Leaves I also give them a light pinch to release even more flavor.
The Lime*** pieces on the other hand I only squeeze the juice from half and add the remaining pieces as is to rather use either the Celery stalks or the straw and give the pieces a little stab every now and then whilst sipping.
This way you control just how limey your drink turns out.
