Cipolla Rossa di Tropea is a sweet red onion variety grown in the Calabria region of Italy, particularly around the town of Tropea. Known for its distinctive deep purple color and mild flavor, it is often used in salads, salsas, and various Italian dishes. This onion is celebrated for its high sugar content and low sulfur levels, making it less pungent than other onion varieties. The cultivation of Cipolla Rossa di Tropea is protected by the European Union's PGI (Protected Geographical Indication) status, which ensures that only onions grown in this specific area can be labeled as such. This recognition highlights the onion's unique qualities and its importance to local agriculture and cuisine.
