Doogh

Iran's ancient cooling drink: tangy yogurt thinned with sparkling water and seasoned with dried mint and salt, the national answer to every summer afternoon

Origin: Persia / Iran

From the journey of Mint.

Doogh (دوغ) is one of the most ancient fermented drinks in the world, a direct descendant of the churned milk beverages of the ancient Near East. Its name derives from the Persian dooshidan, to milk, and the drink was already ancient when Ibn Sina catalogued it in the 11th century. The principle is simple: yogurt (mast), thinned with water, seasoned with salt, and flavoured with dried mint and sometimes dried rose petals or cucumber. What the Armenian tan, the Turkish ayran, and the Indian lassi (salted version) share with doogh is a common ancestor in the pastoral dairy cultures of the ancient Middle East; all are variations on the same idea: fermented milk made potable, cooling, and refreshing through dilution and seasoning. The Iranian version is distinguished by its use of dried mint (rather than fresh), by the preference for sparkling water in the modern preparation, and by a specific salt-to-tang balance that makes it as much a palate cleanser as a drink. Doogh is drunk alongside the most complex and chilli-hot dishes of Iranian cuisine; khoresh (stewed dishes), kebabs, chelo rice; where its cold acidity and mint freshness cut through the richest flavours. Every kebab house in Iran has a refrigerator of doogh bottles. Every summer lunch begins with a glass.

Ingredients

base

  • 200 g full-fat plain yogurt, use the best quality thick yogurt available (Greek-style works well)
  • 250 ml cold sparkling water (or still water, sparkling is the modern Iranian preference)

mint

  • 1 tsp dried spearmint, crumbled between the fingers before using, or 1 tbsp fresh spearmint, finely chopped

seasoning

  • 0.5 tsp fine sea salt, or to taste

garnish

  • 1 pinch dried rose petals (optional, traditional garnish)

optional

  • 4 thin slices Persian or English cucumber (optional, some versions include cucumber)

Method

  1. Combine the yogurt, salt, and dried mint in a jug or bowl. Whisk vigorously until completely smooth; no lumps.
  2. Add the sparkling water and stir gently. The mixture should be the consistency of thin buttermilk; pourable and refreshing, not thick. Adjust water to your preferred consistency.
  3. Taste for salt and mint. Doogh should be distinctly tangy, lightly salty, and clearly minty; not sweet. Adjust accordingly. Chill briefly if not already cold.
  4. Pour into glasses over ice. Garnish with a pinch of dried rose petals or an extra crumble of dried mint. Serve immediately.

Notes

The dried mint used in doogh should be spearmint (na'nā), not peppermint; the menthol sharpness of peppermint would overpower the drink. In Iran, commercially bottled doogh (brands including Kalleh and Ramak) is widely available and often carbonated; the flavour profile is the same as homemade. Some versions add a small piece of cucumber for extra freshness. Doogh is not lassi; it should be salty, not sweet.

🌍Origin

Eastern Mediterranean & Levant — c. 1550 BCE (documented), likely much earlier in folk use

🌱Domestication

Mint was never domesticated through selective breeding of a single wild progenitor in the way that grain crops were. The genus Mentha is exceptionally prone to natural hybridisation; even Linnaeus complained that he could not classify it reliably, because the plants refused to hold stable species boundaries. The principal culinary varieties are a continuum of natural hybrids, selected and stabilised by human propagation: Mentha spicata (spearmint) is itself a natural hybrid of obscure parentage, cultivated since antiquity as the culinary archetype; Mentha × piperita (peppermint) emerged in English fields around 1696 as a spontaneous cross between spearmint and water mint (Mentha aquatica), was identified as distinct by the botanist John Ray, and was subsequently cultivated deliberately for its extraordinary menthol content; Mentha arvensis (field mint or corn mint) is native across Asia and Europe and was domesticated independently in India and China for industrial menthol extraction; Mentha pulegium (pennyroyal) is the ancient Mediterranean species used in Greek ritual drink and Roman medicine, still cultivated for its sharp camphor-mint aroma though not safe in large quantities. The named varieties (Moroccan mint, apple mint, Vietnamese mint, which is actually Persicaria odorata and not a true Mentha, spearmint, and peppermint) represent thousands of years of human selection within a genus that evolution, not agriculture, created. A further species warrants acknowledgement beyond the culinary mainstream: Mentha australis (River Mint), native to watercourses across southeastern Australia from Queensland to South Australia, was used by Aboriginal Australians for millennia before European contact, medicinally for headaches, respiratory complaints, and skin conditions, and occasionally as a flavouring in food preparation. Growing wild along the banks of the Murray-Darling river system and its tributaries, it represents a third independent regional Mentha tradition alongside Mediterranean spearmint and the Asian field mint of China and India, a native herb tradition of considerable antiquity that has not yet entered the modern culinary mainstream as a cultivated ingredient.

Global Voyage

Mint's cultivation history is unusually ancient, already documented in Egyptian medicine by 1550 BCE and named in Greek mythology as one of the oldest plants of the Mediterranean world. Unlike most spices that required dramatic long-distance trade routes to reach new markets, Mentha is native to a broad swath of temperate and subtropical regions across Europe, the Middle East, and Asia, meaning many cultures encountered and developed independent mint traditions from locally-occurring species. The result is a palimpsest of parallel histories rather than a single origin story: Mediterranean spearmint, codified by Greek and Roman medicine, spread through the Roman Empire into Northern Europe and was preserved in monastic physic gardens through the Dark Ages; the Arabic-Persian culinary and medicinal tradition of na'nā spread through the Islamic world from the Levant to Morocco, producing one of the world's great hospitality rituals in Moroccan atay; the independently-occurring field mint (Mentha arvensis) of China and India was cultivated for medicinal use and eventually became the world's largest source of menthol; and the revolutionary English peppermint industry of the 18th century extracted and concentrated menthol from the Mitcham fields of Surrey, producing the sharp, clean-cold mint flavour that became the basis of modern confectionery, toothpaste, and cocktail culture. Each strand is distinct in botany, in culture, and in culinary application; all are connected by the genus name Mentha but arrive at 'mint' from different directions. A fifth thread, less often told, runs through Moorish Al-Andalus: the Islamic na'nā tradition of the Córdoban palace gardens and the Andalusian agronomical manuscripts gave spearmint the Spanish name hierba buena (good herb), which crossed the Atlantic with Castilian colonists to the Andes, where it became the defining herb of Colombia's agua de panela, one of the world's most universally consumed daily beverages and among the very few drinks on earth in which fresh mint is a primary flavouring rather than a garnish.

🍽Modern Culinary Role

Mint is among the world's most widely grown herbs, cultivated on every inhabited continent. Global production centres on three species: Mentha arvensis (field mint, grown primarily in Uttar Pradesh, India and in China, supplying approximately 75% of global menthol for pharmaceutical, confectionery, and personal care applications), Mentha spicata (spearmint, grown in Morocco, Spain, the USA, and the Middle East, supplying culinary mint for North African tea culture and global cooking), and Mentha × piperita (peppermint, grown in the Pacific Northwest of the USA, Oregon and Washington, and in Europe, for confectionery, pharmaceutical, and liqueur flavouring). The four main culinary varieties carry entirely different characters and applications that should not be confused: spearmint (M. spicata) is the culinary archetype: sweetly aromatic, caraway-forward, used in tabbouleh, mint sauce, mojitos, raita, and the majority of cooked mint applications worldwide; peppermint (Mentha × piperita) is menthol-dominant, sharp and cooling, used in confectionery, cocktails, herbal teas, and the classic after-dinner mint; Moroccan mint (M. spicata var. crispa 'Moroccan', sometimes called nana) is a spearmint cultivar with particular sweetness and low bitterness, cultivated specifically for the Maghrebi tea tradition; and field mint (M. arvensis) is the industrial menthol source and the dominant fresh cooking mint across Southeast Asia and China. Pennyroyal (M. pulegium), the ancient Mediterranean species used in kykeon and Roman condiments, is no longer in common culinary use and is not safe for consumption in large quantities. The cultural breadth of mint is unmatched among culinary herbs: it appears in Islam's most widely performed hospitality gesture (Moroccan atay), in America's most ceremonial cocktail (the mint julep), in Lebanon's national salad (tabbouleh), in Vietnamese pho and fresh spring rolls, in British post-dinner confectionery, in Indian street food chutneys, in Persian yogurt dips, and in Greek ritual drinks: a herb that has found a culturally essential role on every inhabited continent.
