These onions tend to be medium to large in size and have a mild to sweet flavor. They are often consumed raw, grilled or lightly cooked with other foods, or added as color to salads. They tend to lose their redness when cooked.
They can be stored 3 to 4 months at room temperature.
Red onion of Tropea
The red onion from Tropea, Italy, (Italian: "Cipolla Rossa di Tropea") is a particular variety of red onion which grows in a small area of Calabria in southern Italy named "Capo Vaticano" near the city of Tropea. This onion has a stronger and sweeter aroma and the inner part is juicier and whiter than other red onions and it is possible to make a marmalade with it. In March 2008, the European Union registered the Protected Designation of Origin mark for the onions produced in this particular area.
