G'dday mate!

I already know that you are from Western Australia...either from the
Perth, Fremantle, or possibly Broome? Western Ausralia is such a big
area that was used by the British in the 1950s to test their nuclear
bomb prototyples during the cold war such as the infamous Maralinga
blast.
The WA is too obvious to confuse with Washington besides youa are
using SRF not cake flourw which should be the norm of household bakers
in the Amercian continent .
Regading Hershey replacement use any natural dark cocoa you can find
in Western Australian market; maybe Coles and Safeway have it.
