In Turkey, Iran, and Syria salep is popular as a restorative and also as a provocative to amatory activity.

The tubers of one [orchid] species, Orchis mascula, produce a flour called salep, which was made into a drink known as "saloop" in 18th-century London, as an alternative to coffee (Charles Lamb thought it the ideal breakfast for chimney sweeps). Salep is a Turkish word with an even more precise derivation (it's from the Arabic for "fox's testicles"). Despite this, the Turks still use it to make a strange elastic ice cream, eaten with a knife and fork, which carries a pungent aftertaste compared by one commentator to the scent of "goats on a rainy day". Salep ice cream is so popular that O. mascula is now a protected species in Turkey.
