Back in the early days, Australian settlers usually survived on meat and damper. Vegies were scarce, and limes and vinegar were sought after to stave off scurvy.
One delicacy of the time was burnt black parsnips, ground into a powder and used as coffee, or for the tea drinker there was a concoction colloquially known as Stick and Rail tea because of the lumps of woody substance in the tea. It was drank very hot, very sweet and very black.
Just imagine if he 'food carers' said that meat, damper and tea could cause cancer...there wouldn't be an true blue Aussie standing now.
