Put in a collins glass one branch of fresh Basil, 4 Lime wedges, 50 ml of white Rum and a teaspoon of fine Brown Sugar. Then take the back of a wooden spoon or a muddler and just keep on stirring, until the sugar is dissolved and everything is muddled up. Put in some Ice, top of with Soda water. Herby, yummie, refreshing goodness (especially if you don't like mint...)
