Recipe

• 1 part Scotch whisky

• 1 part Campari

• 1 part red vermouth

Pour into an old-fashioned glass filled with ice, and add a thick half-slice of orange. About 25ml per part should do it.

This is a variation on one of my all-time favourites, the Negroni, just substituting the gin for whisky. The result is striking, with the Negroni's searing bitterness still present, but a curious dark twist from the whisky replacing the crisp, clean gin. Every sip was fascinating, and, like its gin-based cousin, it can be savoured for hours. Just make sure to use plenty of ice.

It's nice to see Campari and whisky together in a well-known cocktail with an established name. I had thought it was just an innovation of my friend Ms Villa, but I'm glad to see people have been enjoying it for years.

The original recipe uses rye whiskey instead of Scotch. I imagine rye would be a lot smoother, but I haven't tried it.
