It was fairly early in my first visit to Australia that I encountered the iconic confections called Lamingtons. These traditional sweets consist of rectangles of sponge cake dipped in melted chocolate and rolled in shredded coconut. Hard to beat that combination. I found them from one end of Australia to the other. Here’s a video that takes you through the whole process of making them — though one can simply buy sponge cake, rather than making it from scratch.
For Americans, be advised that caster sugar is what we call super fine sugar. If you don’t have super fine, just put regular granulated sugar in a blender for a few seconds. Icing sugar is what we call powders sugar. Corn flour is corn starch. And 180 decrees Celsius is about 350 degrees Fahrenheit. I think everything else will be familiar. Hope you enjoy this Aussie classic.

Certainly not the most astonishing discovery I made while traveling in Oz, but definitely a fun and tasty one — and among the several iconic foods that make me think of Australia.
