I am a great believer in offering the sort of stuff everyone can knock back without justified hesitation. I think I have told you before that - due to its mood-enhancing properties - prosecco is known chez moi as prozacco. Well, unsurprisingly, this is a drink that forms the foundation of my liquid entertaining. My favourite of all is a drink introduced to me by Anna del Conte, called Prosecco Sporco, which involves pouring a glass of prosecco and then adding a dash or two of Campari. Prosecco sporco literally means 'dirty prosecco' but somehow Filthy Fizz sounds better to me. I find it unutterably chic and absolutely gorgeous into the bargain. The bitterness of Campari is not to everyone's taste (though the bitterer the better, as far as I'm concerned) so if you are wanting to turn this into a cocktail for the sweeter toothed, I suggest a dash of Chambord black raspberry liqueur instead, if you happen to have that in your drinks cupboard.
