Doogh

Doogh is a cold and savoury drink made with fermented milk. Unlike its sister beverage of Turkish origin, Ayran, Doogh is not simply diluted yogurt. According to the Ministry of Food Standards in Iran, Doogh "is a drink resulting from lactic fermentation of milk whose dry matter is standardized by diluting yogurt (after fermentation) or buttermilk (before fermentation)."^[1] The manufacturing process of Doogh involves a sometimes lengthy period of fermentation in warm temperatures, which comes to be the ultimate cause behind this drink's savoury taste.
