Red onions

Originally from Central Asia, onions were brought to Central Europe by the Romans and to Germany in the 19th century. Today, Egypt, Hungary, and China are among the most important suppliers.

Onions contain vitamins B6, B7, and C, as well as potassium, calcium, sulfur, phosphorus, chloride, sodium, and manganese.

Onions are best stored in a dark, dry, cool place, such as a cellar or pantry.
