Callout is a type of scallion or green onion known as calçot in the Catalan language. The calçot from Valls (Tarragona, 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, they sprout into 4–10 shoots, roughly the shape of small leeks or scallions.
