Great question. Yes the loaf size is a little larger, it is actually back to its original intent. The hydration has been decreasing and the loaf size too, but if you went back to our origins 4/2020 you would find that it isn’t that different. Regarding the 8 1/2 “ pan. That has never been the size. That you’ve made it work is certainly fine. You might end up making some rolls with extra dough or you can standardize to the 9 x 5 size. I’m all for making use of what we’ve got, but it is also nice to build a consistent loaf for our food bank families. I’ll leave it to you and thank you for all the great bread baking you are doing!
