Mix together hot water, salt, margarine, brown sugar or honey.
Dissolve 4 tablespoons yeast in 1 cup warm water. Mix in whole wheat flour (and some bran or whatever you feel like), then add yeast mix, then white flour. You will add flour until it feels "right" - flour quantity will depend on humidity, etc.
Raise once until doubled, then divide into 4 loaves. Raise again. Bake at 325 °F for 35-40 minutes.
Notes
Substitutions
Butter and Margarine: Butter is a dairy product made from cow’s milk. Margarine typically contains milk or soy, but there are milk-free and soy-free versions available.
Gluten: Gluten is a protein found in specific grains (wheat, spelt, kamut, barley, rye). Other grains are naturally gluten-free but may have cross-contact with gluten-containing grains. Look for certified gluten-free products if you need to avoid gluten. Find out more about wheat and gluten substitutions.
