The server was surprised we didn’t know about it but he was a Indo-Fijian waiter. Basically the vanilla ice cream took the place of butter. We had it two different places and neither were really geared to Americans. In fact, think we were maybe the only Americans. Lots of Aussie type stuff like the flavorless sausage they eat (at least the ones I tried).
It is actually pretty tasty with maple syrup. We have done it a couple of times at home.
