Rub a lemon wedge around the rim of a chilled coupe or martini glass. Dip the rim into a small plate of sugar to lightly coat (optional).

Fill a cocktail shaker with ice. Pour in the Hennessy Cognac, orange liqueur, and fresh lemon juice.

Shake the mixture vigorously for about 15 seconds until well chilled.

Strain the cocktail into the prepared glass and garnish with a lemon or orange twist, if you like.
