In an episode of "Bizarre Foods" Ethiopia, the host tasted something similar to pop-corn that instead of using corn kernels, used Sorghum seeds. The preparation is the same as when you do pop-corn, the taste is however different. It's richer, nuttier and there is no annoying shell that sticks in between your teeth. The size of the "Pop-corn" Is smaller compared to the regular pop corn. These seeds are very versatile and they are used to make couscous, porridge and even molasses.
No, they are called the same way "Sorghum Seeds" And they also have Sorghum flour. The seeds are super tiny but they carry a lot of flavor. They contain calcium, magnesium, potassium and iron.
