The term doogh occurs in Persian sources from at least the 11th century. Traditional doogh developed through dairy churning: butter was removed and the remaining cultured liquid was consumed, while modern versions usually combine yogurt with still or carbonated water, salt, and herbs.
Origins & development
Doogh is deeply established in Iran and the wider Persianate and neighboring pastoral food world. This recipe follows a contemporary Iranian home and restaurant style rather than recreating sheepskin-churn production.

The Persian word doogh is documented from at least the 11th century, when it referred to a skimmed or churned dairy drink. Traditional production separated butter from cultured milk in a churn, leaving a tangy liquid; contemporary home doogh is more often made by diluting yogurt with still or carbonated water and adding salt and herbs. Closely related yogurt drinks occur across neighboring food cultures.
