Vegemite is a concentrated spread made from yeast extract. To be specific, it's the leftover dregs of yeast used in the beer brewing process (I used to work at Kraft Foods and got the whole factory visit!) It's black and sludgy and looks like something you'd use to patch up potholes in the road. Getting hungry? It smells like a mix of rotting shoes and salt. It's one of those things you either hate or love. I am firmly in the hate category. I'd rather spread my car oil on toast than that stuff

Witchetty grubs are kind of like a big centipede without the legs, but fatter and yellow and white in colour. Apparently you throw them on the campfire and eat them whole. It's more of a protein food for Aboriginals who are still on the land and intrepid travellers. Luckily we have those supermarket things Isn't it amazing how we grow up with food biases?
