Perhaps a relocation over to Recipes and Other Non-language Topics would be in order if anyone wants to pursue this.

MMMM, lamingtons! Chocolate are my favourite, but strawberry are not bad. I did feel a little guilty posting the original query, but it was more about the etymology of the name for the biscuits - I don't want to know how they're made! I agree that to avoid even the hint of inappropriate digression, any further enquiries shall be posted in the "non-language" topics, even though my query was language-related.
