PROBLEM IDENTIFIED - Previously good WW/Oat/Bread Flour recipe not rising
I have been baking nearly all our bread using bread machines for many years. I do several different kinds (Plus Pizza and Rolls) using pre-measured packets we make ourselves. I recently moved and had to use another source of flour for our latest packets.
Our white bread packets have been working fine - but we cannot get out old reliable breakfast bread recipe to rise AT ALL. It's 1.5 cops bread flour, 1.5 cups whole wheat flour and 1 cup quick oats, 1/2 cup dry milk, 1/2 tsp salt. 2 tbs oil and 1 tsp lemon juice, 1 1/3 cups water and a 1 tbs dry yeast.
I knew my yeast was good because it was working on everything else. So, I tried making up a batch measuring all ingredients instead of using the packets - it rose a little. So, I did a test replacing the WW flour with Bread Flour. Of course it rose like crazy.
So, I have it narrowed down to the WW flour. Wondering if I bought the wrong kind, or if something else could be wrong with it. Any ideas what the problem is and/or how I can get the packets to rise?
