Hey KinkyOne, got back in May from 2 weeks down under with Aussie friends. They rented a 6 person van and drove us (2 Seattle area couples) all over South East Australia, staying in VRBO homes all along the way. Graeme converted me to a regular "black and tan" for breakfast daily. Proper preparation is take a piece of toast and butter it to the edges, next, spread peanut butter over half of the toast, finally, spread a very thin layer of Vegemite over the other half, enjoy, repeat if necessary. Graeme convinced me that this was a well established Australian custom. A few days before we left, we met up with his daughter- who promptly told me with a huge smile, that "black and tans" were a creation of only her father, and no one else in Australia did that. In our travels, we even drove by the Vegemite factory!
