Mmm, Vegemite. It's good, though potent for those not used to it, sharp and savoury, though less intense than the British Marmite. Good to spread thinly with some butter and cheese.
There's also the new Vegemite Cheesybite variant which you
can spread thickly, as it's milder and creamier thanks to the Kraft cream cheese mixed into it. I love them both.
