Turkish soup (çorba) is served at the beginning of every formal meal and at midnight after a wedding — it is both daily sustenance and ceremonial preparation. The Turkish çorba tradition encompasses lentil (mercimek çorbası), yogurt (yayla çorbası), wheat (ezo gelin), tripe (işkembe), and dozens of regional preparations. The unifying technique: most Turkish çorba are finished with a terbiye (an egg-lemon or egg-flour liaison) that simultaneously thickens and brightens the broth, or with a red pepper butter swirled at service.
**Mercimek çorbası (red lentil soup):** - Red lentils cooked with onion and tomato paste until completely dissolved - Blended smooth then strained — the strain produces the characteristic velvet texture - Finished with a swirl of butter infused with dried red chilli and dried mint: the butter is browned, chilli added, the mint steeped briefly, then poured at service in a long swirl across the surface - The terbiye option: beaten egg yolk with lemon juice tempered into the hot soup — simultaneous thickening and souring **Yayla çorbası (meadow soup):** - Rice in yogurt-based broth, finished with a dried mint and butter swirl - The yogurt is stabilised with flour before adding to the hot broth (identical to Indian kadhi stabilisation) - Dried mint: added to the butter swirl rather than to the soup itself — the butter extracts the fat-soluble aromatic compounds from the dried mint, distributing them throughout the soup surface **The finishing swirl:** - Hot butter with dissolved red pepper and/or dried mint poured at service in a decorative swirl - This is not purely aesthetic — the hot fat drops dissolve fat-soluble aromatic compounds from the pepper and mint and distribute them across the soup surface, providing aromatic top notes that wouldn't be present if the spices were added during cooking Decisive moment: The terbiye application. Egg yolk beaten with lemon juice must be tempered into the hot soup gradually — a small ladleful of hot soup added to the egg-lemon mixture first, then the tempered mixture returned to the pot. Adding the raw egg directly to the hot soup produces scrambled egg ribbons rather than a smooth thickening.
