When you are ready to drink some hot salep, the bulbs can be ground into a powder and mixed into hot milk for 10-15 minutes to arrive at the ideal consistency. The key to good salep is a thick viscosity as the bulbs contain 50% plant mucilage which enables them to sprout new bulbs. This contains glucomannan, a natural thickener now used as a food supplement. Thanks to its thickening properties, the orchid powder is also a key ingredient in traditional Turkish Maraş dondurmasi ice cream which mixes goat milk and sugar with salep. The orchid powder acts as a binder and increases the melting temperature, keeping the ice cream solid longer.
Many ancients believed salep had healing powers including calming ulcers, clearing phlegm, preventing miscarriage, curing venereal diseases, warding off scurvy, and even righting drunkenness. The orchids of Turkey were not the only ones used medicinally. People around the world have long used orchid roots, stems, and flowers to cure a variety of ailments. The Cherokee used the yellow-fringed orchid for headaches and the Chinese made shihu from Dendrobium nobile for digestion to name just a few examples.
The widespread global demand for orchid bulbs, whether as a medicine or just a hot drink, has threatened many orchid populations. In order to protect some of the species endemic only to the Anatolian peninsula, Turkey has technically outlawed the exportation of wild bulbs since 1989, although enforcement seems to be lax. Now, commercial harvesting has moved to Iran, where there is growing concern that the wild population of orchids is diminishing.
Due to the scarcity of pure salep, substitutes make for cheaper, more convenient options. The majority of salep drank today has little to no real salep powder in it. Among the substitutes we might find in our thick, white drinks are rice powder, guar gum, and carboxymethyl cellulose (CMC). While the powders of these substitutes make instant salep possible (whereas real salep takes time to mix), the true flavor of the traditional Turkish tipple has been lost. Real salep should be nearly flavorless, but these substitutes often mix in artificial flavors like vanilla to create an entirely new, but equally viscose, drink. Substitutes, while unauthentic, may present the only sustainable option in the long run for those who want to drink salep without endangering wild species of orchids.
Before decrying substitutes as unauthentic, consider the orchids and try some salep. Popular commercial powders make a thick, almost marshmallow-like concoction. These white drinks are creamy and frothy with nutty and vanilla undertones—maybe even reminiscent of yams. Sprinkle a bit of cinnamon or cardamom on top and you won’t be so concerned about how many orchids died for your drink. In fact, you may find yourself thinking of the Greek myth of Orchis and wondering what would happen if the drink really did contain orchid roots.
