Although I can't pinpoint the exact origin of the first Ayran drink recipe, I wouldn't be surprised if the Assyrians were responsible. However, the internet seems to speculate that it most likely originated in Persia or Turkey. In Iraq, this drink is known as "Shanina." In Iran, it's known as "Doogh." "Doogh" according to Wikipedia, is derived from the word "Dooshidan," (or "milking"). However, this Aryan drink recipe is not to be confused with the Indian yogurt drink known as "Lassi." Lassi is a sweet yogurt drink, usually containing fruit and spices, for example, cardamom.
