Lamingtons are an important part of Australian culture. You'll find them at all cake stalls. We have lamington drives (which is where school kids for example, sell them by the dozen to raise money). We have lamington cakes. We have the lamington national park. Lamingtons are lovely.

My mum used to make them.
You can also cut them in half and fill them with jam and cream. That's an exceptional way to have them although very rich.
Yes, lamingtons although they may be humble, are a very important subject.
