Prosecco cocktail, ‘Sbagliato’

With no signs of the craze for Prosecco slowing down after New Years, here’s a cocktail to soak up all the extra bottles you may (or may not) have leftover. Called a Sbagliato, or “mistake” in Italian, it’s much more fun than tired old Bellini (Prosecco and white peach); basically, it’s a Negroni with the Gin replaced by Prosecco.
Two parts Prosecco to one part Campari and one part Martini Rosso (or sweet vermouth is also fine).
Two drops of Angostura bitters, optional.
Pour over ice and stir.
Garnish with a slice of orange in a large wine glass.
