Bitter Union

Chill a martini glass by placing it in the freezer or filling it with ice water for a few minutes.

In a cocktail shaker, combine the gin, Campari, maraschino liqueur, freshly squeezed orange juice, and freshly squeezed lime juice.

Add ice to the shaker and shake vigorously until the mixture is well-chilled.

Strain the shaken cocktail into the chilled martini glass.

Garnish the drink with a flamed orange peel to enhance the aroma and presentation.
