Our co-op buys from http://www.clnf.org/ a couple of times per month (which is when one of their drivers comes to our area). Several of the ladies buy 50lb bags of wheat and grind their own flour. My children *love* their fruit leather (and I love that it’s FRUIT and not HFCS).

I use my Vita Mix to grind my grain… even though I don’t have the ‘dry’ container. My old Vita Mix lasted 30 years without the dry container, I’m just careful to grind in batches that won’t overheat the motor. ( 3 cups or so.. and then start over. Definitely enough to make a big batch of bread)

I also buy these items in bulk that I haven’t seen listed above:
molasses
baking powder
vanilla
oils
vinegar
salt
baking soda
oatmeal
rice
millet

Grind about 10 cups of (wheat montana brand preferably) wheat flour (can mix barley, rye, spelt, etc too-but make sure it’s at least 2/3 wheat)
Dump the wheat in the bowl of the bosch.
Add:
1/3 cup wheat gluten (any grocery store sells it usually)
3 Tablespoons dough enhancer (it’s mainly powdered vitamin C to keep it fresh longer)
1/3 cup SAF instant yeast. (BUY THIS IN BULK-TOO EXPENSIVE AT A STORE. Even Ebay has okay prices)

Blend those dry ingredients together. Then add:

1 cup honey
1 cup Olive Oil
6-1/2 cups Hot Water(not boiling-don’t want to kill the yeast!)

Blend together until it’s a wet dough. Then, grind a few more cups of flour and sprinkle 2 cups on top of the mixture. Sprinkle 2 Tablespoons of sea salt on top of that. Blend it in slowly and add more flour gradually until the dough starts to pull away from the sides of the bowl. Knead in Bosch on high for about 3 minutes, until the gluten is developed (long “strings” start to form on the surface of the dough)

Let rest in bowl 10 minutes (loosen lid of bowl or it will explode!!!)

Slam on board greased with Olive Oil a few times to release the air bubbles. Shape into six loaves. Rise until double (covered with light cloth) Bake in loaf pans. Eat! Freezes well.

The same dough also makes great cinnamon rolls, orange rolls, dinner rolls, parmesan and herb rolls, hot dog buns, sandwich buns, etc. I use it for everything.

Also, I have a Bosch Universal that I got from here: http://www.pleasanthillgrain.com/bosch_universal.aspx that I love. I can make 6 loaves of #2 each made of 100% whole wheat. I can do that in about an hour total, so if I am having a very industrious day, I can bake several dozen loaves and I sell some to local people to help pay for the grain. I usually charge about $6 (it’s all organic, with local honey and olive oil) but one lady insists on paying me $10 per loaf!

The things I recommend buying in bulk:
Grains! ALWAYS store these in food buckets.
Nuts
Seeds (for sprouting or grinding and mixing with flour)
spices (whatever you’ll use in 6 months, but they’re MUCH cheaper this way)
Dried fruit
BEANS (great cheap meal when you have no money! )
honey (I buy a gallon at a time, sometimes 5 gallons)
SALT (the good stuff! )
