This variation on a classic Rusty Nail recipe bumps up the bitterness with the addition of Campari. Anyone who loves Negroni style cocktails should give this a try.
2 1/4 oz Jameson Irish Whiskey
3/4 oz Drambuie
3/4 oz Campari
Stir all ingredients with ice and strain into a cold glass with one or two ice cubes and a twist of orange.
