A pavlova (or "pav") is basically a giant meringue- egg whites and sugar- all poofed up and slowly cooked to make a crackly mound with a soft, marshmallow-esque center. The tartness of the passion fruit puree really compliments the sugary meringue.
I could have made the pavlova from scratch- it seems pretty easy- but Amy had given me a container of an Aussie pav shortcut: Pavlova Magic, the equivalent of American boxed cake mix. It was pretty foolproof, if not magical, once the internets converted the directions from Celsius to Fahrenheit for me.
The best part about Pavlova Magic, though, is that it comes in this weird egg-shaped packaging. It's like all of the '80s era L'eggs pantyhose packaging died and went to Australia to be reincarnated as Pavlova Magic containers:
