Without it you must use some white flour to get a loaf to rise, My doctor won't let me use white flour since it can cause a rise in blood sugar. Told me to eat 100 percent whole wheat bread. The vital wheat glutton takes the place of added white flour. I only use 1 table spoon to the whole wheat flour.
I make my bread in a Hamilton Beach bread machine instead of the way I used to make my bread. The bread machine does a very nice job except for the paddle getting stuck in the loaf and has to be removed with forcepts when the bread cools.
