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.
I am definitely an amateur cook but quickly realized cooking with sorghum flour was easy.
