@antedeluvian Wow, thanks for the primer in Rhodesian delicacies! I can't really cast aspersions on your dietary pleasures as when I was a kid I used to love a sandwich consisting of peanut butter, mayo, and lettuce! Granted a notch or two above sardines and condensed milk, but barely. :-)
Dion't knock until you've tried it. But surely you know it as a coke float. There were high brows amongst us Rhodesians who maintained that coke with ice cream was a coke float and that a brown cow was coke with milk. Searching the 'net, I see that brown cow now has Khalua implications and there were times that a brown cow combined ice cream and root beer (unknown in Rhodesia) whilst black cow used coke.
As to other South African delectables that may give you pause:
Bunny Chow: a hollowed out loaf of bread (only van would have it sliced) filled with curried vegetables/meat
and my personal favourite (to churn my stomach): sardines and condensed milk. Condensed milk is pretty much diabetes in a can and the salt of the sardines is supposed to enhance the sweetness, if that were possible.

One of my father's favorites when he was a lad was ginger ale (not Verner's :-) with a scoop of vanilla ice cream. His jocular grandfather would have the same, but he'd add some whiskey to it and call the drink a "mule's neck".
I grew up in Wisconsin, so Van is replaced with Ole (sometimes adding Sven and/or Inga). Ole is by default Norwegian, unless you're Norwegian in which case Ole is Swedish. If you're half-Norwegian and half-Swedish, Ole is Danish.
Speaking of which (International Wing of the Old Jokes Home):
A Scandinavian ocean liner shipwrecks on a desert island. One year later, the Norwegians have built a fishing boat, the Finns have cut down all the trees, the Danes have formed a coöperative and the Swedes are still waiting for someone to introduce them to each other.
