8 cups flour (if you'd like an all whole wheat mix, use whole wheat
pastry flour from health food stores)
2 cups whole wheat flour
1 1/2 cups buckwheat flour (at some markets, but for sure at health
food stores. Optional)
1/2 cup cornmeal (stone ground)
1 1/2 cups oatmeal (blend in your blender till powdered)
2 cups buttermilk powder (this is in the baking section of your
market)
5 tablespoons baking powder
2 tablespoons baking soda
1 cup sugar (or sucanat-natural sugar at the health food store)
2 tablespoons salt
This will make four quarts. Mix all together in a very large bowl and
divvy up into gallon sized freezer storage bags. I would mark the
date with a Sharpie pen and keep it in the freezer although you can
keep in your pantry.
