Cold sauces & condiments
labneh
لبنة · Labneh is a thick, tangy cold sauce and spread made by straining full-fat yogurt through cheesecloth until it loses roughly half its weight in whey. The result is a cream-cheese-like paste with pronounced lactic tang, bound by milk proteins and milk-fat globules, preserved by salt, and finished with olive oil and aromatics. It is a foundational condiment across the Levant, used as a dip, a sauce, a sandwich spread, and a platform for seasoning.
The formula
2 : 1 (yogurt : labneh by weight, after 24–48 h straining)
The 2:1 weight ratio is the master ratio. Yield depends on fat content and straining time: 24 h yields looser labneh (~55% recovery); 48–72 h yields firmer labneh (~45–50% recovery). Full-fat yogurt is non-negotiable for proper texture. Salt at 1–2% of yogurt weight.
Identity
- Strained fresh yogurt — never cooked, never heated after straining
- Full-fat (minimum 3.5% milkfat) — skim or low-fat yogurt produces a loose, grainy result
- Whey drains freely for 24–72 hours; the paste should hold its shape on a spoon
- Salt added at 1–2% of the original yogurt weight as the sole preservative and flavor anchor
- Finished with good olive oil as a delivery medium, not mixed in
Ingredients
| Base | full-fat plain yogurt (minimum 3.5% milkfat) | Greek-style unstrained yogurt is a convenient starting point but adds a cooked yogurt flavor. Fresh, unpasteurized or gently pasteurized yogurt with live cultures yields the cleanest lactic character. |
| Seasoning | fine sea salt | 1–2% of yogurt weight (10–20 g per kg). Salt slows fermentation, draws moisture through osmosis, and seasons the finished paste. |
| Fat | extra-virgin olive oil (for finishing) | A generous pour over the finished labneh creates an oxygen barrier and adds flavor. The oil is not mixed into the paste for storage; it is added at service. |
| Aromatics | za'atar, dried mint, black pepper, or garlic (at service) | Seasonings are applied at the table or just before serving, not during straining, to preserve their volatile aromatics. |
Method
- 1Combine yogurt and salt in a non-reactive bowl, stirring until the salt is fully dissolved.Salt dissolves immediately in the liquid phase and begins drawing moisture out of the curd matrix from the first moment. This jump-starts whey separation and ensures even seasoning throughout.
- 2Line a fine-mesh strainer with two layers of cheesecloth (or a clean cotton nut-milk bag), set it over a deep bowl, and pour the salted yogurt in.Two layers of cheesecloth prevent fine curd particles from escaping while allowing whey to drain freely. A deep bowl accommodates the volume of whey without overflowing.
- 3Tie the cloth loosely, or fold it over the yogurt, and refrigerate for 24–72 hours.Cold-temperature straining slows unwanted acid development while allowing controlled whey expulsion. Room-temperature straining works faster but risks over-fermentation. The longer the straining, the firmer and more concentrated the paste.
- 4Twist and squeeze the cloth to extract remaining whey, then transfer the dense paste to a clean bowl.Manual squeezing recovers an additional 5–10% paste that clings to the cloth. The paste should hold a clean spoon without dripping — if it slides off, it needs more draining time.
- 5Taste and adjust salt; serve at room temperature or chilled, pooled on a plate, finished with olive oil and aromatics.Serving temperature affects texture: cold labneh is firm and paste-like; room-temperature labneh spreads more luxuriously and releases aromatics more fully. The olive oil is a finishing element, not a mixing medium, forming a seal against oxidation.
Techniques that matter
Straining (syneresis induction)
Yogurt is a gel network of casein proteins with entrained water and whey. Mechanical pressure and osmotic gradient force the liquid whey out through the cloth while retaining the protein-fat matrix. The result concentrates flavor and texture.
Controlled fermentation
The yogurt's live cultures continue metabolizing lactose to lactic acid during straining, deepening tang over time. Cold temperatures moderate this activity. Salt suppresses undesirable bacteria and yeast while allowing desirable lactobacillus strains to continue.
Osmosis (salt action)
Salt creates a concentration gradient across the curd membrane. Water follows the gradient out of the gel, accelerating syneresis and firming the texture. This is the same principle as in fresh cheese making (ricotta, paneer).
Acid development (fermentation flavor)
Yogurt's lactic acid content is already present; additional acid development during straining (at room temperature) deepens the tangy, complex flavor. Cold straining preserves a milder, fresher lactic character.
Variations & derivatives
Labneh balls (labneh makbous or labneh spheres)Syria, Lebanon, Jordan
Labneh is rolled into small balls (often by hand, with salted hands) and stored submerged in olive oil with dried herbs. The oil acts as a preservative and a serving medium.
Labneh with tarator (sesame paste)Palestine, Lebanon
Labneh is thinned with tahini and lemon juice to create a pourable sauce for grilled meats. The tahini adds bitterness and emulsification; the result is looser and more sauce-like.
Labneh with tomato and sumacLevantine (general)
Labneh is mixed at service with diced fresh tomato, sumac, and parsley — essentially a cold sauce for flatbreads. The tomato's liquid is folded in to loosen the paste.
Labneh kashkawanTurkey (kashar/labneh cross)
Sheep's-milk yogurt is used for a more assertive, complex tang. This reflects the broader regional tradition of strained fermented dairy across Anatolia and the Caucasus.
Labneh with date molasses and pistachiosGulf countries (modern)
A sweet-savory presentation: labneh drizzled with date molasses (dibs) and scattered with crushed pistachios, served as a breakfast component.

Substitutions
- full-fat yogurt → Greek-style unstrained yogurt (2× strained) — Contains the same fat and protein profile but has already been partially cooked in pasteurization. Produces acceptable labneh with a slightly more cooked yogurt flavor.
- labneh → Greek-style cream cheese (or crème fraîche thinned with yogurt) — Commercially available cream cheese approximates the texture and fat content of labneh but lacks its lactic tang and the characteristic fermented complexity.changes result
- labneh → sour cream (as a cold sauce) — Sour cream is a thin, fermented dairy with a similar tang but a pourable consistency. It can stand in for labneh as a cold sauce for shawarma or kebabs but cannot substitute for the spread or dip form.changes result
Troubleshooting
Labneh is too loose and watery after 48 hours
Yogurt fat content was too low (under 3%), straining was too cold (below 4°C but insufficient time), or the yogurt was pre-strained (Greek-style) and already partially drained → Return the loose paste to fresh cheesecloth and continue straining. If using Greek-style yogurt as a shortcut, start with unstrained yogurt or accept a lower yield with a more acidic, liquid character.
Labneh is overly sour or fermented — tastes like cheese gone bad
Straining at room temperature for too long allowed excessive acid development by non-desirable organisms. The texture may also have become grainy from over-acidification of the casein network → Use cold straining for a fresher, milder result. If over-sourness is a flavor goal (some preferences favor it), the labneh is safe to eat — sourness in this context reflects intentional fermentation, not spoilage. Reduce straining time to 24 hours for a milder paste.
Labneh separates in storage — liquid pools on top
The paste was not adequately strained before storage, or salt was not mixed in uniformly. The liquid is whey that has not been fully expelled → Stir the whey back into the paste before serving, or drain briefly before using. Ensure salt is fully dissolved in the yogurt before straining begins.
