Laurel Kerosene, and "Aussie" Ice Cream

Another find today at the Sunday Market -- a recipe book put out by Vacuum Oil under its Laurel kerosene brand, before Vacuum became Mobil. I have no idea as to date, but the booklet was printed in Wellington.

What intrigued me was this entry:

I asked two of my favourite West Islanders about this, Jayne from Our Great Southern Land, and Leechbabe from Stuff with Thing, why this particular recipe is an "Aussie" one. The answer's still uncertain, as one lead raised, the cornflour, seems to be fairly common in ice cream making (thanks, Jayne and Leechie for your help!)

Further suggestions as to the reason for the Aussieness of the recipe gratefully appreciated.

Update: The ice cream has been made at Jayne's place today. The results:

"Ok, ice cream isn't fully set yet but VERY yummy.
Has that decent 'real food' taste, no synthetic after-taste, if you know what I mean?
We'll be making this ice cream instead of buying any from now on."

 Cool. Glad my habit of gathering up old stuff at markets has helped trans-Tasman relations!
