There are two theories. The first theory is that this symbol is called "Alceringa", which means "dream time". It was used by aboriginal Australians to describe what they believed was the "other" state of being. They were baffled by what happened when one fell asleep, what we today refer to as dreaming. So, they gave a name to this other world that one entered during a slumber - Alceringa, the Dreamtime.
The other theory is that it doesn't actually mean anything, and it's just a neat-looking printer's symbol.
It might be a reference to Bombay vindaloo, which incorporates peppers.
