Bread with wheat starch for PKU
I am using wheat starch to bake, due to a medical diagnosis for my son. No matter what I do, my bread will not rise in my bread machine. I get a somewhat decent rise in the first cycle. after the pucnh down, I do not get another rise. I am using active dry yeast that I purchased in bulk. I also proof it and the yeast is good. I am substituting wheat starch for wheat in recipes. I am adding oat fiber and a special protein to my flour to mimic the makeup of wheat flour. My "made up flour" is approximately 70% starch, 15% protein and 15% fiber (which is higher in fiber than usual flour). Any assistance would be helpful. I do not have the time to deal with a starter and do not have any interest in it. I need a bread recipe that can start and stop in one day, or be done in a bread machine. I basically need help figuring out why my recipe won't work.
