Things You'll Need
Seed test screens
Buckwheat can be used for breakfast cereal or flour, depending on how it is ground. Although its name is misleading, buckwheat is actually a fruit. Buckwheat has no gluten in it, so it provides a good alternative flour for people who are on gluten-free diets. If you grow your own buckwheat, you need to remove its hulls before you can use it.
Sift your buckwheat through a seed test screen to separate the smaller pieces. When you run the buckwheat through a grain mill, its precise setting will break the hulls apart as long as they are all the same size. If you don't sift the buckwheat first, you will be left with small, intact hulls in your ground buckwheat.
Set your grain mill to the size of the buckwheat hulls, and run a handful of them through the mill as a test. If the setting is too large, the buckwheat will come through unhulled. If the setting is too small, the mill will grind up both the hulls and the buckwheat inside them. Aim for a setting that breaks up the hulls but leaves the interior buckwheat whole.
Grind all your buckwheat using the mill at the correct setting.
Resift your buckwheat through a seed test screen with smaller holes. With the right screen, all of the broken hulls will remain on top, and all the hulled buckwheat will fall through.
Spread the buckwheat out on a tray outdoors and blow across it. This will sift out bits of hull and dust left from the grinding process.
Store your buckwheat in a sealed container. Use the buckwheat as a cooked breakfast cereal, or grind it into flour for pancakes and bread.
Save your buckwheat hulls to use as stuffing in traditional pillows.
