Qurut (Kurut): Central Asia’s Dried Sour Yogurt Balls and How to Make Them

Qurut is Central Asia’s answer to the question that nomadic peoples solved long before refrigeration existed: how do you carry a year’s worth of dairy protein on horseback? The answer is a dried fermented yogurt ball so concentrated, so intensely sour and salty, that it keeps for months or years in a saddlebag and reconstitutes into a nourishing drink or soup with nothing more than water. From Afghanistan to Kyrgyzstan to Uzbekistan, qurut is one of fermentation’s most elegant inventions.

At a glance

Qurut (kurut) is Central Asian and Afghan dried yogurt: sour yogurt strained thick, salted, shaped into small balls and dried hard. It's eaten as a salty snack or soaked and crushed into a sour sauce. Kyrgyz kurut is dominated by Lactobacillus and averages about 15% protein, but home-made kurut has measured about 3.5 times the 2–3% salt standard. At home, make it from pasteurized-milk yogurt with 2–3% salt and dry it completely.

  • Strained, salted, shaped and dried yogurt from Central Asia and Afghanistan.
  • Kyrgyz kurut bacteria: mainly Lactobacillus, with Streptococcus, Enterococcus and Lactococcus.
  • Kyrgyz kurut averaged 14.6% protein and 1.8% fat.
  • Home-made kurut had about 3.5 times the 2–3% salt standard.
  • Dry it hard right through – soft centers can mold.

Qurut – kurut in Kyrgyz and Kazakh, qurt in Uzbek, close kin to Mongolian aaruul – is yogurt that has been strained, salted, shaped into small balls or discs and dried until hard. It’s sour, salty and chalky, eaten as a snack across Kazakhstan, Kyrgyzstan, Uzbekistan, Tajikistan and Afghanistan, and soaked and crushed into a sour liquid that dresses Afghan dishes such as ashak and kichri qurut. Like many dried dairy foods of pastoral peoples, it turns summer’s milk into something that keeps through winter.

What’s in It

Qurut starts as a lactic ferment. Sequencing of kurut from several regions of Kyrgyzstan found Lactobacillus the dominant bacterial genus, followed by Streptococcus, Enterococcus and Lactococcus (Yegin et al., 2024). An analysis of eight common Kyrgyz kuruts found an average of 14.6% protein and 1.8% fat – and a lot of salt: home-made kurut contained about 3.5 times the 2–3% salt set by the standard, while two factory brands had 5.8–5.9%. Kurut was eaten by about 80% of 7,251 Kyrgyz teenagers surveyed, and daily by about one in five, which led the authors to call for less salt (Kochkorova & Kitarova, 2021). So enjoy qurut as a salty snack or seasoning, not a protein bar.

Making It Safely

Traditional qurut is often made from raw milk. Raw milk can carry harmful germs that souring doesn’t reliably remove (CDC), so the recipe card starts with yogurt made from pasteurized milk – see our yogurt guide, or use plain live store-bought yogurt. Strain it thick, salt it at about 2–3% of the strained weight, and dry the balls somewhere warm and airy until they’re hard right through. In humid weather, use a very low oven: balls that stay soft in the middle can grow mold. Discard any with fuzzy mold. Central Asia’s other fermented milks include Kazakh camel-milk shubat.

Relatives

Strained yogurt is a whole family: fresh labneh, spiced and aged shanklish, and Turkish tarhana, where yogurt and grain are fermented and dried together.

Recipe: Homemade Qurut

Makes
About 30 small balls (about 350 g)
Hands-on
40 min
Fermentation
Yogurt 6–8 hours; strain overnight; dry 3–7 days (or 8–12 hours in a low oven)
Salt
2–3% of the strained yogurt's weight
Temperature
Yogurt at 40–45°C; drying warm and airy, or oven at 50–60°C
Difficulty
Easy

Equipment

  • Cloth-lined colander
  • Scale
  • Drying rack or tray
  • Clean cloth or mesh cover

Ingredients

  • 2 litres plain yogurt (homemade from pasteurized milk, or store-bought live yogurt)
  • 2–3% of strained weight salt (about 15–20 g for 700 g strained yogurt)
  • Optional pinch of ground cumin, dried herbs or chili

Method

  1. Pour the yogurt into a cloth-lined colander over a bowl and strain in the fridge overnight, then squeeze or press until thick and crumbly.
  2. Weigh the strained yogurt and knead in 2–3% of that weight in salt, plus any seasonings.
  3. With wet hands, roll into balls about the size of a walnut, or press into small discs.
  4. Dry on a rack in a warm, dry, airy place, covered with mesh or cloth, turning daily, for 3–7 days until hard right through. In humid weather, dry in the oven at 50–60°C for 8–12 hours instead.
  5. Store fully dried qurut in an airtight jar in a cool, dry place.
  6. Discard any pieces that stay soft in the middle, smell off, or grow fuzzy mold.

Frequently asked questions

What is qurut?

Dried, salted sour yogurt from Central Asia and Afghanistan, shaped into small hard balls and eaten as a snack or dissolved into sauces.

What does qurut taste like?

Very sour and salty, with a chalky texture that softens as you chew.

How is qurut used in cooking?

In Afghanistan it's soaked in water, crushed into a sour liquid and spooned over dishes such as ashak and kichri qurut.

Is qurut healthy?

It's a concentrated source of milk protein and calcium, but it's very salty – home-made kurut has measured far above the salt standard – so eat it in small amounts.

How long does qurut keep?

Fully dried and kept airtight in a cool, dry place, it keeps for months. Discard any that soften or mold.

Is qurut the same as kashk?

They're relatives: Persian kashk is a sour dairy product sold as a liquid or paste, while qurut is dried into hard balls.
