@farmerman,
(Not that I wish to create a digression from this birthday thread, but ...)
When you say "biscuit" it's sort of a cross between bread & pastry, farmer? (going by the link engineer posted) We mean a different thing by the same term in Oz. More like crackers (savoury), or what you'd call cookies (sweet), I guess.
Anyway the idea of adding chilies & eating biscuits with gravy is very mysterious indeed! But I can tell from your description that it was very good.
(Years ago, a good soul here sent me a packet of Bisquick all the way from the US, after Gus ( I think) talked at length about what an amazing wonder food it was!
I had fun playing with it. (thanks, r. Bet you've forgotten you did that!)
No amount of explaining could get the the idea of what this wonder food actually was.)
