In soil, most of the zinc stays bound to the solid particles. When high levels of zinc are present in soils, such as at a hazardous waste site, the metal can seep into the groundwater. Industries also can release dust containing higher levels of zinc into the air we breathe.
Add sorghum to a large pot of water. Use one cup of whole grain sorghum to three cups of water. Bring to a boil, reduce to a simmer and let cook for approximately 40-55 minutes or until the sorghum is tender. Drain any remaining liquid and serve.
Sorghum is a type of grass containing a cereal grain, much like wheat, oats, or barley. It was originally native to Africa, but has been cultivated in many other parts of the world, including North America, for at least 150 years.orghum flour is very dry, though, and can be tricky to bake with. Cornstarch can help to compensate for this dryness, so that baked goods made from sorghum flour come out moist instead of crumbly. For best results, add one tablespoon of cornstarch for every cup of sorghum flour.
