Sgroppino - from Venice with a twist. Chill a stainless steel cocktail shaker in the freezer. Once ice, use a small whisk to mix 50g softened lemon sorbet with a splash taken from 90ml of prosecco. Slowly whisk in 30ml limonello, then add the rest of the prosecco at an angle. Stir in a little Campari to taste, serve in Champagne flute. Serves 1.
