Step 1Before mixing, prepare a cocktail glass as follows: Rub a slice of lemon around the rim of the glass and dip the glass in superfine sugar so the sugar adheres to the edge of the glass.
Step 2Pare half a lemon in a one-piece spiral; arrange the lemon peel spiral to line the inside of the glass.
Step 3Fill a small cocktail shaker with one-third cup cracked ice. Add the Cognac, Curacao, maraschino liqueur, lemon juice, simple syrup and bitters. Shake well. Strain into the prepared cocktail glass.
