Salep is a flour made from the tubers of the orchid genus Orchis (including species Orchis mascula and Orchis militaris). These tubers contain a nutritious, starchy polysaccharide called glucomannan. Salep flour is consumed in beverages and desserts, especially in places that were formerly part of the Ottoman Empire where it is a traditional winter beverage. An increase in consumption is causing local extinctions of orchids in parts of Turkey and Iran.
It is sometimes served with iced coffee at certain coffee shops.
