Fresh squeezed lime juice Superfine sugar or simple syrup Mint Rum Soda water
In a tall glass muddle mint and superfine sugar. I love the muddling process: it releases the oils in the mint and mashes sugar against its leaves. Add an ounce of lime juice, a shot of rum, lots of ice. Add soda water, a splash of simple syrup if you like, and garnish with a sprig of mint.
