There is a web site dedicated to Vegemite ... produced by Kraft foods. I've yet to try it ... something to do with brewery yeast ... and loaded with "B" vitamins.
Got that ... now what the @#?? is a "Dandenong"?
Someone once said that the Platypus was proof that the Great Creator drank hard spirits once in a while. I have this image in my mind's eye of the first explorer to discover this animal, reporting to his boss, "... Uh, you are not going to believe this, but..."
LOL . Yes Vegemite, might fall into the same category. Ya either love it or hate it. It's black and sticky, smells funny, full of vitamin B, made with the help of Bovines and made across the ditch(!) So on first appearance, doesn't seem to have much going for it .
