The European Commission approved the addition of a Portuguese onion to the register of Protected Designations of Origin (PDO). ‘Cebola da Madeira' is the name given to bulbs produced using traditional practices on the islands of Madeira and Porto Santo. The aroma is distinctive and when cooked, they become milder and acquire smoky, grilled or caramel notes, while maintaining their intensity and complexity.

The parish of Caniço on the island of Madeira is particularly important for the production of ‘Cebola da Madeira'. On the island of Porto Santo, this crop is part of the strategic objective of safeguarding, enhancing and optimising the island's agricultural and cultural resources.
