The aromatic and medicinal plant, which has many sorts, has a long history of cultivation and was cultivated in Egypt more than 4,000 years ago. But it took a long time until the onion, which is originated in the steppes of Central Asia, found its way to Europe with the help of Roman soldiers. Once there, the onion has quickly become an indispensable ingredient – as in many other parts of the world. For use as a spice, the onion is first dried and then processed into flakes, powder and granules.
