The term 'Dried Tubers of Orchids' refers to the edible root of certain species of orchids. The most common type is Salep, which is a flour made from the dried tubers of orchids and used in many Middle Eastern and Mediterranean dishes. Salep has a sweet, nutty flavor and is often used as a thickener in soups and desserts. It is also used to make a hot drink called salep dondurma, which is popular in Turkey.
