Su böreği — "water börek" — is the most labour-intensive börek preparation: yufka sheets are boiled briefly in salted water before layering with cheese filling, then baked. The boiling produces a completely different texture from standard baked börek — the sheets become silky and slightly yielding rather than crispy, and the finished börek has the texture of a light, savoury pastry rather than a flaky one. It is considered the most refined börek style in Istanbul.
- **The yufka:** Homemade is traditional — each sheet rolled thin, then briefly boiled and spread on a cloth to dry slightly. - **The boiling:** Each sheet cooked for 30–45 seconds in salted boiling water — just long enough to become pliable and slightly translucent but not so long that it becomes gluey. - **Immediate transfer:** To an oiled surface, brushed with butter immediately to prevent sticking. - **The filling:** Beyaz peynir (Turkish white cheese) + eggs + parsley — the egg binds the cheese into a cohesive layer. - **The assembly:** 3–4 boiled sheets, buttered, with cheese filling between every second sheet.
