calçot

Calçot () is a type of green onion. The name calçot comes from the Catalan language. The calçot from Valls (Catalonia, Spain) is a registered EU Protected Geographical Indication.

Calçots are milder and less bulbous than onions and have a length of between 15 and 25 cm (white part) and a diameter of 1.7 to 2.5 cm at the root. Planted in trenches, like an onion, as a single bulb, and successively increasing the depth of the soil around the stems throughout autumn and winter (see earthing up), they sprout into 4–10 shoots, roughly the shape of small leeks or scallions.
