Just to redeem my small town grocery store - I looked at all the containers in the store and they all said practically the same thing -
10JUN04 Which I read as June 10, 2004 - I think it actually means June 4, 2010. LOL - Sort of written backwards to my mind, but I believe I was reading it wrong.
I just think there were a variety of things done wrong - cake flour made through substituting, mixing incorrectly, not adding the sugar until after everything was mixed.
Anyway, I think I am going to use my original recipe that I have tried and scale up as suggested earlier.
Thanks all and you are welcome to a good laugh over my baking powder misread.
