No No NO!
Vegemite is NOT a cheesy spread. It is a vegetable/yeast extract spread. It's black, it's kinda salty-ish and it looks like boot poilish.. but it's soo good. It is nothing like marmite or promite... those are both vile!
Just recently the released a new version of Vegemite which is combination (supposedly) of vegemite and cream cheese. But it tastes nothing like that combination and is vomituous. It is called Vegebite cheeymite.
Hope that makes sense. If not google Kraft Vegemite!
