Kishk is a fermented mixture of bulgur wheat and yogurt that’s dried into a shelf-stable powder, and making it at home requires just three ingredients and about a week of patience. The process is simple but unhurried: you combine bulgur and yogurt, let the mixture ferment for several days with daily kneading, then dry and grind it into a fine powder that keeps for up to two years.
What You Need
The traditional ratio is roughly one part bulgur to two and a half parts yogurt by volume. A good starting batch uses 1 cup (200 grams) of fine bulgur wheat, 2½ cups (625 milliliters) of plain full-fat yogurt, and 2 teaspoons of salt. That’s the entire ingredient list. Use the best yogurt you can find, ideally one with live active cultures and a thick, tangy character. Whole-milk yogurt works well. Some traditional recipes use goat’s milk yogurt, which produces a more pungent, complex flavor, but cow’s milk yogurt is perfectly standard.
Fine bulgur is the right choice here. Coarse bulgur takes longer to absorb the yogurt and produces a grainier final texture. If you can only find medium bulgur, soak it in water for 30 minutes and drain it before mixing with the yogurt.
The Fermentation Process
Start by combining the bulgur, yogurt, and salt in a large bowl and mixing thoroughly. Cover the bowl with a clean cloth or loose lid and leave it at room temperature. Each morning for the next seven to nine days, knead the mixture thoroughly by hand. This daily kneading, sometimes called “khabit” in Lebanese tradition, is the heart of the process. It redistributes the lactic acid bacteria naturally present in the yogurt, ensuring even fermentation throughout the mixture.
Over the first few days, the bulgur absorbs most of the liquid and swells. The mixture thickens, develops a pleasantly sour smell, and begins to taste increasingly tangy. By day three or four, it should have a porridge-like consistency. If the mixture seems too dry and crumbly during fermentation, you can add a few tablespoons of yogurt and knead it in. By the end of the week, the flavor should be distinctly sour and the texture cohesive, almost like a thick dough.
The lactic acid bacteria doing the work here are diverse. Several species contribute to the final flavor, including strains that produce the sharp tanginess and others responsible for the more rounded, savory notes. The fermentation also lowers the pH enough to inhibit harmful bacteria, which is part of what makes kishk so remarkably shelf-stable.
Drying and Grinding
Once fermentation is complete, you have what’s known as “kishk akhdar” or green kishk. This fresh version can be rolled into small balls and preserved in olive oil, but most people continue to the drying stage to make the classic powder.
Spread the fermented mixture in a thin layer on clean baking sheets lined with parchment paper or on clean cotton cloths. Traditionally, this is done outdoors in direct sunlight, and in a hot, dry climate the kishk dries in two to three days. If you’re drying indoors, use your oven set to the lowest temperature (around 150°F/65°C) with the door slightly cracked, and expect it to take 6 to 10 hours. You can also use a food dehydrator at a similar temperature. Break up any large clumps partway through to speed things along.
The goal is to reach a moisture content between 8 and 12 percent, which in practical terms means the pieces should be completely hard, brittle, and easy to snap. If any piece still feels pliable or slightly soft in the center, keep drying. Underdried kishk can develop mold during storage.
Once fully dried, grind the pieces into a fine powder. A spice grinder, blender, or food processor all work. Traditionally, women rubbed the dried pieces between their fingers to break them down, though today most people use a mill or electric grinder. Sift out any stubborn large bits and grind them again.
Storage
Dried kishk powder is exceptionally stable. Stored in a jar at room temperature, it keeps for up to two years without spoiling. It doesn’t readily absorb moisture from the air the way many dried foods do, so even a loosely sealed container works, though an airtight jar is ideal if you live in a humid climate. There’s no need to refrigerate it.
Nutritional Profile
Kishk is more nutritious than you might expect from a simple wheat-and-yogurt product. Per 100 grams of dried powder, it contains roughly 18 to 21 grams of protein, 62 to 69 grams of carbohydrates, and 6 to 11 grams of fat. The fermentation process makes some of the nutrients in both the wheat and the yogurt more bioavailable, and the powder retains beneficial lactic acid bacteria depending on how it was dried. It’s calorie-dense, which is part of why it was historically a survival food in rural mountain communities across Lebanon and Syria.
How to Cook With Kishk
The most common use is a thick, warming soup. Whisk about 3 to 4 tablespoons of kishk powder into a cup of water in a small saucepan, then heat over medium while stirring constantly until the mixture comes to a boil and thickens. The consistency should be similar to a creamy porridge. Some people finish it with a drizzle of olive oil and a pinch of garlic fried in butter. Others add caramelized onions or small pieces of dried meat.
Beyond soup, kishk powder works as a seasoning. Sprinkle it over roasted vegetables, stir it into bread dough for a tangy flavor, or mix it with olive oil and spread it on flatbread before baking. The sour, slightly cheesy flavor pairs well with rich or fatty foods.
Regional Variations
What’s called kishk in Lebanon and Syria has close relatives across the Middle East, though they differ in meaningful ways. Iranian kashk is made from milk (often sheep’s milk) that’s boiled, fermented, and had its butter removed before being shaped into balls and dried. It may or may not include wheat. The result is more of a concentrated dairy product with a whitish appearance, quite different from the golden, grain-heavy Lebanese version. In Turkey, a related product called tarhana uses tomatoes, peppers, and onions alongside yogurt and flour, giving it a distinctly different flavor. Iraqi kushuk represents yet another variation. All share the core principle of fermenting dairy and drying it for preservation, but the ingredients, techniques, and final flavors are distinct enough that they’re really separate foods rather than interchangeable versions of one dish.
