2 parts gin
2 parts Campari
1 part sweet vermouth
Orange peel
Rosemary sprig
Shake gin, campari and sweet vermouth in an ice in a shaker. Set aside.
In a highball glass, fill half way with chartreuse. Place orange peel and rosemary sprig in chartreuse filled glass.
Light the liquid on fire. Smother the flame with the glass end of a chilled martini glass. This captures the smokiness in the glass. Pour over strained Negroni mixture from shaker. Garnish with orange peel and rosemary sprig from the chartreuse glass.
