Instructions:

Fill a shaker with ice cubes.

Pour the gin, lemon juice, maraschino liqueur and crème de violette into the shaker if desired. If using orange bitters, add them now as well.

Shake vigorously for 10–15 seconds or until the outside of the shaker has frosted over slightly from condensation on the metal surface - this indicates that it is very cold inside!

Strain into a chilled martini glass or coupe glass and enjoy!
