Since ancient times, the plant Lathyrus clymenum has been grown exclusively on the islands of Santorini, Thira, Thirasia, Palea Kameni, Nea Kameni, Aspro, Christiani, and Askania in Cyclades prefecture solely to produce Fava Santorinis.
These islands have a very hot and dry climate and volcanic soil, which give this product its unique character. Fava Santorinis are dried, husked, and crushed embryonic leaves that are yellowish in colour and shaped like flattened discs. After the husks are removed and the seeds separated, the product is packed in order to prevent it from absorbing humidity.
