Doogh
دوغ · Doogh is a savory, salt-tangy Persian/Afghan yogurt-based liquid preparation built from cultured dairy, water (still or carbonated), salt, and mint. It functions simultaneously as a refreshing beverage, a table condiment, and a foundational pourable component used in cold soups and as a marinade base across Iran, Afghanistan, and the wider Middle East/Central Asia.
The formula
1 : 2–3 yogurt : cold water (or 1:1 with soda water for sparkling style)
Yogurt volume to dilution liquid; some commercial and home recipes use a 1:1 carbonated ratio (e.g. Bon Appétit: 2 cups whole-milk yogurt to 2 cups club soda). Traditional table doogh runs thinner (more water).
Identity
- salty-tangy
- yogurt-cultured
- mint-scented
- pourable
- traditionally Persian/Afghan
- can be still or sparkling
Ingredients
| Culture | plain full-fat yogurt (traditional, not Greek/strained) | Full-fat provides body and emulsification; stirred (not strained) yogurt is traditional so the doogh stays opaque rather than thin. |
| Liquid | cold water, still or as soda/club soda | Flat water for still doogh; carbonated water for doogh-e gazdar. Cold temperature prevents the yogurt from splitting. |
| Seasoning | salt | Non-negotiable — doogh is a savory, not sweet, preparation. Dosage is variable to taste. |
| Aromatics | dried mint (or fresh mint leaves) | Dried spearmint is the classic choice; fresh mint is a brighter modern option. Optional rose petals or black pepper fall in the same role. |
Method
- 1Place yogurt in a bowl or jug and whisk until smooth and pourable.Yogurt that has settled or firmed in the fridge needs loosening so it will incorporate the water without forming lumps.
- 2Add salt and dried mint; whisk or pulse in a blender to disperse.Salt only dissolves fully in the dairy phase, and mint needs to be broken up so its aroma is distributed evenly rather than floating in clumps.
- 3Slowly stir in the cold water (or, for sparkling doogh, the cold soda water) while whisking.Adding liquid gradually prevents the yogurt from breaking or splattering; pouring soda onto the side of the jug preserves carbonation (Easy Persian Recipes).
- 4Taste and adjust salt; chill thoroughly before serving.Salt perception increases as doogh cools, so the final seasoning is set just before service, not at the first whisking.
Techniques that matter
Whisking vs. blending
Blending (as in Bon Appétit) pulverizes mint into fine flecks and homogenizes the yogurt; gentle whisking keeps a lighter, slightly looser texture with visible mint.
Side-of-jug soda pour
Pouring carbonated water down the inner wall of the jug — instead of into its center — reduces fizz loss and keeps the doogh visibly sparkling (Persian Recipes).
Variations & derivatives
Doogh-e Gazdar (Sparkling Doogh)Iran, broad
Made with soda or club soda instead of still water for a fizzy finish (Ashpazkhune, Bon Appétit).
Doogh-e Sadeh (Still Doogh)Rural Iran / Afghan home kitchens
The traditional 'everyday' doogh, diluted with plain cold water; thinner and lower-effort than the sparkling style.
Rose-Petal DooghPersian festive cooking
Adds dried rose petals (and sometimes a grind of black pepper) for a perfumed note (Bon Appétit).
AyranTurkey, Caucasus, Balkans
Closest regional cousin — same yogurt/water/salt template, typically no mint (Linsfood).
Lassi (savory)India/Pakistan
Shares the yogurt base but is usually thicker and seasoned differently; cited as the South Asian parallel (My Persian Kitchen).
Used in these dishes
Substitutions
- Greek/strained yogurt → plain stirred yogurt thinned with extra water — Greek yogurt needs significantly more liquid to reach traditional doogh body and can taste chalky if used undiluted.
- fresh mint leaves → dried spearmint, crushed — Dried mint is the traditional choice; use roughly 1 tsp fresh = ~¼ tsp dried. Flavor profile shifts from bright-green to earthy.
- club soda → plain cold water — Loses carbonation and fizz; add a pinch of baking soda only if seeking a manufactured 'sparkling' lift — not recommended.
- regular table salt → kosher or flaky sea salt — Halve the volume if switching to fine table salt, which is denser per spoon (Bon Appétit: 1 tsp Diamond Crystal = ½ tsp Morton).
Troubleshooting
Doogh separates or looks grainy
Yogurt was added to liquid too quickly, or liquid was warm → Whisk vigorously or re-blend, and always start with cold water/soda to keep the emulsion stable.
Too thick
Yogurt was too dense (Greek-style) or not enough water → Whisk in additional cold water a splash at a time until pouring consistency is reached.
Goes flat immediately
Soda water was stirred or shaken too hard into the yogurt → Pour carbonated water down the inside of the jug, fold gently with a fork, and serve straight away (Persian Recipes).
Mint clumps on the surface
Mint was added after dilution or without being crushed → Crush dried mint between palms (or blend with the yogurt) before adding liquid so the flakes stay suspended.
