The classic Burgundian aperitif snack of gruyère filled choux pastry is often served with a glass of fizz to guests on arrival. In Burgundy the fizz will sometimes have a dash of cassis liqueur to make the traditional kir royale but just as often a glass of chilled white or even light red Burgundy is served. A classy dry white Bordeaux or pinot gris from Alsace or New Zealand would be perfect too.
