Cut the lemon into small cubes. Put all but 1 lemon cube, the basil, and brown sugar together in a glass and muddle until the consistency of a paste or jam. Fill a glass with ice. Pour rum and sweet and sour mix into shaker without ice. Put cap on and shake; this blends the spirit with the mixer and creates a "froth". Strain into glass and stir. Garnish with small spring of basil and cube of lemon and serve immediately.
