"Antique" sourdough starter??
I recently purchased a Sourdough Jack cookbook from a local library book sale. The copyright info suggests that it was printed in 1966...and there is a package of dried sourdough starter still attached to the book. Does anyone know if it would still be safe to use?
The package said it was 65 years old (so if that was 1966, that makes it 108 years old now) and i'm very intrigued about using it. Also, I haven't been able to find much about Sourdough Jack Mabee, other than book listings and references to his recipes. Does anyone know more about him? I'm assuming he has gone to that great Sourdough sponge in the sky by now...his picture in the book looked old then and that was 43 years ago.
