OK, it's crazy cold out so I'm stuck at home with my baby & it feels like a great day to make bread. However, the only flour I have in the house, somehow, is whole wheat pastry flour. I know pastry flour is really not meant for bread so it's not ideal but will it make acceptable bread in a pinch? How would I adjust the amount if substituting for AP flour? Or should I just make biscuits or something instead?
