This is a delicious way to turn a simple sparkling white wine into a sophisticated cocktail. Probably not the time to use expensive champagne.
1 measure Dubonnet
1 sugar cube
2 dashes Angostura bitters
Champagne or sparkling wine, chilled
Orange peel, to decorate
1. Pour the Dobonnet into a chilled flute.
2. Add the sugar lump with the bitters splashed onto it.
When ready to serve, pour on the chilled bubbly and add a twist of orange peel.
