Doogh is Persia’s answer to ayran – a sparkling yoghurt-based drink that has been part of Iranian cuisine for centuries and remains one of the most popular beverages in Iran, served with meals, at celebrations, and throughout summer. It shares the basic structure of other yoghurt drinks in the region (yoghurt, water, salt) but is distinguished by two features: the use of sparkling water rather than still, and the flavouring with dried mint, which is characteristic and immediately recognisable. It’s an acquired taste for some and an immediate favourite for others.
The Recipe
Combine 200g full-fat plain yoghurt with 200ml cold still water in a blender and blend for 60 seconds until completely smooth and slightly frothy. Pour into a glass over ice and top up with 100ml of cold sparkling water – pour gently along the side of the glass to preserve the carbonation. Stir briefly and season with a generous pinch of salt and a half teaspoon of dried mint (crumbled between your fingers before adding to release the oils).
The ratio of yoghurt to water can be adjusted to preference – more yoghurt produces a thicker, creamier drink; more water makes it lighter and more refreshing. Start with equal parts and adjust from there. The salt level is a matter of taste – some people want it noticeably salty, others prefer just a hint. The dried mint is not optional in doogh the way it is in ayran – it’s the defining flavour and the element that distinguishes doogh from a plain yoghurt drink.
Variations
Rose and cardamom doogh: add half a teaspoon of rosewater and a pinch of ground cardamom. This version is more floral and slightly sweeter – some people add a small amount of honey. It’s traditionally served at Persian celebrations and weddings. Cucumber doogh: blend a quarter of a cucumber with the yoghurt and water before adding the sparkling water. The cucumber adds a cooling, green freshness that works particularly well in very hot weather. Fresh herb doogh: replace the dried mint with fresh mint and add a small amount of fresh coriander or basil. Blend with the yoghurt rather than sprinkling on top.
What to Drink It With
Doogh is traditionally served alongside rice dishes, grilled kebabs, and stews (particularly the herb-heavy Persian stews like ghormeh sabzi and fesenjan). The carbonation and dairy fat in the yoghurt cut through the richness of stewed meat and rice in the same way that lassi works with Indian curries – it’s a functional pairing as much as a cultural one. Cold doogh alongside something heavily spiced or fatty is genuinely more refreshing than any other beverage option.
For anyone unfamiliar with the flavour profile: think of the sparkling mineral water sold in the Middle East with a slightly savoury finish, but considerably more creamy and filling. It takes about three sips to decide whether you love it. Most people who persist past the initial unfamiliarity become converts.
