Before you exclaim in horror at drowning a pretty parrot, even in champagne, rosella is also the name of a native Australian fruit. You can buy them preserved in syrup, for example, and one of these makes a sculpturally interesting (and flavoursome, but not overwhelming) addition to a glass of champagne. A change from strawberries.
Should you be fortunate enough to be at a table also containing macadamias, runny brie and sliced pear, and other such toothsome nibblies, well, you're in luck.
And if that table is surrounded by charming, funny friends, and has happy and varied conversation entertaining them, well, how good is that?
