Mix up this tasty and complex cocktail with just three ingredients - and equal parts as well. With gin, sweet vermouth and Campari as the ingredients you have an herbal, citrusy flavor bomb whose attributes change while it's sipped.
Add ingredients to mixing glass and fill with ice. Stir for about 30 seconds or until well-chilled, strain into a rocks glass with one large cube or sphere. Garnish with an expressed orange peel.
