I have been trying to replace the butter in a whole grain bread recipe with a sufficient amount of flax seed (1 tablesppon of butter to 3 of flax seed). Unfortunately, the bread doesn't seem to rise as as much as I need it to.  I bake this break for PB&J sandwiches and the little sandwiches are sort of sad.  The original recipe is:

3/4 c water

1.5(minus 3 Tbs) c WW flour

3 Tbs wheat gluten

1/2 c oat flour

1/4 c almond flour

1.5 Tbs dried milk powder

1 Tbs butter  (being replaced with 3 Tbs of flax seed meal)

2 Tbs honey

1 tsp salt

1 tsp yeast

I have tried to reduce the flour a little to compensate for the extra solids in the flax seed meal.  I have also tried slightly more yeast (and a new batch of yeast).  Neither has helped much.  I am baking the bread in a 1 Lb zojirushi. If anyone has any suggestions please let me know.  Thanks.
