Turkish cooking — particularly in the Southeast (Gaziantep, Şanlıurfa, Adıyaman) — uses a wider range of souring agents than any other tradition: pomegranate molasses (nar ekşisi), sumac water, dried tamarind, green plum (can eriği), sour cherry, unripe grape (koruk), and verjuice. Each produces a distinct sour dimension: pomegranate molasses is the most complex (sweet-sour with deep fruit notes); sumac is fruity-tart; koruk is sharp and astringent; tamarind is deep and slightly resinous.
**Nar ekşisi (pomegranate molasses):** - Made from sour pomegranate juice reduced to a thick syrup — approximately 8:1 reduction - The reduction caramelises some of the pomegranate's sugars while concentrating its citric and malic acids - Used in acılı ezme (the spicy meze), in köfte preparations, as a dressing for grilled meats - Commercial nar ekşisi varies enormously in quality — fresh-made from sour pomegranates is irreplaceable; sweetened commercial versions produce a different, less complex result **Koruk (unripe grape):** - The juice of unripe (green) grapes before they develop sugar — extremely tart, with tannins from the skin - Used in specific Antep preparations as a souring agent in the same way verjuice is used in French cooking - [VERIFY] Dagdeviren's specific koruk applications **The sour flavour philosophy:** In Southeastern Anatolian cooking, the sourness is used aggressively — not as a background note but as a primary flavour dimension equal in importance to the hot (chilli), salt (cheese, olive), and fat (olive oil, tail fat). This is the same four-flavour-balance principle documented in Hot Sour Salty Sweet (HS-01) but expressed through a completely different set of souring agents.
