Barley, rice and other flours

Ever wish you had barley flour? Or rice flour? Those things are expensive to buy, but if you have a good blender or a grain mill, you can make your own easily. They're grains, just like wheat. Get it? You can even make bean flour from dry beans (uncooked!).

Manual Grain Mill: A Practical Appliance

A hand operated grain mill is a practical kitchen appliance. In a pinch, you can grind popcorn for corn meal; grind peppercorns more easily than a pepper mill, grind coffee beans, wheat, barley and even make bread crumbs if your bread is dry.
