Borrowed from French salep, from Turkish salep, from Arabic سَحْلَب (saḥlab, “type of orchid”). According to the Oxford English Dictionary, the Arabic word is said to be a contraction of خُصَى الثَعْلَب (ḵuṣā ṯ-ṯaʿlab, “fox testicles”) (الثَعْلَب (aṯ-ṯaʿlab, “fox”) + خُصًى (ḵuṣan, “testicles”)), referring to the testicle-like root tubers.

- 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.
