Lived in New Zealand from 1982 to 1984 and I tried it once as it and Vegemite are popular down there. Certainly was not my taste, but hey, I was only twelve to fourteen years old back then.
I wonder how it is on wallaby?
Marmite or Vegemite, either is one the more difficult to acquire acquired tastes. Brits, Aussies, and Kiwis possess it as a sort of birthright.
Given I have been known to eat rice, eggs, scrapple, and kimchi for breakfast, t should be no surprise a jar of vegemite is in the pantry.
OTOH I do not like mac and cheese.
