Sorghum syrup is, generally speaking, something you only see in households in the upper Midwest. Sorghum, like sugar cane or wheat, is a grass. It produces heads the size of corn ears that contain small seeds, about the size of millet. Farmers once grew sorghum for cattle feed. The grain itself is nutritious, and the stalks can be stored and fermented into silage, i.e. edible compost that cows can live on during the winter.
