Recipe I stole from somewhere else, the ingredient list is not what I created, but the directions and the last part about the raisins are mine:
Makes two "good sized" loaves.
3 cups of spent grain (wet)
1.5 cups warm (~100 F) water
1 package, or 1 tablespoon dry Bread yeast
1/3 cup sugar (I have used brown sugar and honey, I prefer honey now.)
3-8 cups flour (this number is actually guess-work. You will have to know the feel when the dough is "right")
Dash of salt (optional)
Proof Yeast in a mixture of water and sugar (or sugar substitute). Place spent grains in a large mixer (make sure your mixer has balls. Otherwise, you may have to do the kneading by hand. I have been using a Kitchen Aid Artisan, and it has worked for me.) Add yeast mixture to mixer and slowly mix in some flour until a bread hook is needed. Continue adding flour to the mixer, using the bread hook, until the dough is "just right" (almost no stickiness, some is ok, but not too floury. If too floury, add a very small amount of water and recheck). Place dough ball into a large bowl, cover with a clean towel, place in a warm place (my stove has a pilot light, so I use that), until the dough has risen to about twice it's size. Punch down, and split into 2 even loaves onto a baking sheet (I now apply olive oil to the underside of the loaves, to prevent them from sticking to the baking sheet after cooking), and let those loaves rise to about twice their size. Bake in the oven at 350 degrees Fahrenheit for 30-45 minutes, or until cooked fully by checking with a toothpick. Let loaves cool off while still on baking sheet before trying to remove, otherwise the bottoms may separate.
I have experimented with this recipe by adding 1.5-2.0 cups of raisins and 1 tablespoon of cinnamon to the dough while kneading, and have had AWESOME results.
