I have tried a Witchery Grub. It is one of those things that if you go on any outback tour you will end up being offered. I don't think I could take a raw one but cooked they are rather pleasant, in taste not in looks. Then again I can't eat a raw oyster but I like oyster kilpatrick.
It is a bit of 'I dare you to try' this type of stuff. There is nothing wrong with it, it is just protein and if you need the food you eat it. There is nothing more odd with it than any other weird creature or fruit.
I remember being very nervous of eating emu, crocodile and buffalo. They were all nice experiences, nicely cooked. I have had kangaroo tail on a bush fire and that was OK. Messy but it was just meat.
One of the nicest meals was many years ago. My wife and I where in far North Western Australia and living on a beach for a few weeks in our swag. We fished for our food and just cooked the fish over an open fire. Some Aboriginal people joined us and used some herbs they had collected and the fish went from fish to total delight. No better meal has been had, and very few times have I had better company. Nice memory, thank you for stirring it.
