This is my staple:
2 1/2 cups warm water
1 1/2 T yeast
1/3 cup honey
3 Tbl oil
1 Tbl salt
4-6 cups whole wheat flour
1 cup oatmeal
4 Tbl vital wheat gluten
Dissolve yeast and honey in water. Let stand for 15 minutes.
Mix in remaining ingredients using only enough flour to make a soft and slightly sticky dough. Knead 10 minutes (I use my kitchenaid mixer).
Butter pans while kneading. Divide into 2 equal parts. Shape into loaves and place in bread pans. Let rise until double (approx 45 minutes). Bake at 350 for 30 minutes.
This recipe produces a nice dense bread. My dh, however, hates dense bread unless it is pumpernickel. So, I usually let it rise in the mixing bowl, punch it down and then divide in place in bread pans to do a second rise. This makes a lighter loaf.
Over the years I have tweaked with it. Sometimes I do a combo of less honey and some brown sugar. Sometimes I use replace a cup of wheat with rice flour, or barley flour, or whatever other grains I have on hand for milling.
