Well my bread recipe is:
4cups ww flour
4cups warm water
3 tbsp yeast
This will be simmilar to cake batter. Let rise until large bubbles form on surface and dough is doubbled in size. About 2 hours.
Then add:
3/4 tsp salt
1/2 cup oil (olive or vegitable)
1/2 cup honey or mollasis (each adds a diferant flavor to the bread, experiment and see whic you like better or you can mix them half and half)
up to 1 cup cooked grains.
I sometimes also add a cup of one of the following or a mix: sunflower seeds, flax seed, steel cut oats, multi grain mix.
I then kneed in 4-6 cups ww flour (how much flour depends on the ambiant humidity and what else you have added to the mix) kneed for about 15 min. Rise until doubbled, about 2 hours. Shape into loaves, rise another 2 hours. Bake at 375 for 30min. Makes 3 loaves.
For muffins, I will just add between 1/2cup and one cup of cooked grains to any regular muffin recipe.
