Djmat:
What did your DH's family call it? I haven't found anyone else who calls it Prockas.
Sometimes I think my grandmother made up the name. English was not her first language and she couldnt read and write in any language but she still would write down phone messages in some unknown alphabet and half the time she couldn't read it either. I found it so frustrating when she lived with us, I was a teenager and you know how IMPORTANT telephone calls are at that age. She was an interesting character, God rest her soul.h
I make it a lot in the winter and it's good for when I am trying to diet (that's all the time, but without success) as there is no added fat and not that much brown sugar.
Coincidence, too, I live in upstate NY, where do you inlaws live? Did your DH grow up here?
