Add sugar to a small plate. Make two twists from orange rind, by cutting strips with a paring knife or vegetable peeler (try not to get any of the bitter white pith). Cut a wedge from remaining orange and wipe it around the rim of each glass. Dip rims in sugar and add one piece of rind to each glass.
Fill a cocktail shaker with ice. Add brandy, triple sec and lemon juice. Stir vigorously until beads of sweat form on outside of shaker. Strain into prepared glass. Serve immediately.
