That’s not only popular in Oz… it’s huge in England too, but goes under the name of “Marmite” there. MMM, salty yeast spread. I must admit, it does go well on toast—I was surprised at how edible it is.
the advertising slogan for Marmite in the UK is ‘you either love it or hate it’ and i’ve found that to be true most people either can’t get enough of it, or think it’s disgusting :D
