The Swan Prince
A good prosecco, not too sweet (recommended: Nino Franco Rustico)
A good cognac (recommended: Courvoisier or Remy Martin, though Landy is good)
Take a pair of chilled champagne flutes; pour no more than a quarter of the glass with cognac.
Splash in a little Benedictine (don’t get carried away).
Fill the rest of the glass with prosecco.
Serve immediately with hazelnuts and chocolate or a plate of mild cheeses and fruit.
