Created by Beefeater Gin to show off their Beefeater 24 London Dry Gin; this variant of the Negroni will suit those not used to the bitter taste of Campari.
Half-fill a mixing jug with ice.
Add the liquid ingredients, excluding the prosecco, and stir until chilled.
Strain into a champagne flute.
Top off with the prosecco.
Garnish with a raspberry.
