Slow-roasted lamb shoulder appears across every Mediterranean and Middle Eastern tradition — the Greek kleftiko, the Turkish kuzu tandır, the Moroccan mechoui, the Palestinian mansaf. The technique is identical across all: a tough, collagen-rich cut cooked at low temperature over a long period until the collagen converts to gelatin and the meat yields completely. Jerusalem's version uses the spicing of the region — baharat, cinnamon, allspice — but the technique is universal.
Lamb shoulder (bone-in) cooked at 160–170°C for 3.5–4 hours, covered for the majority of cooking, uncovered for the final 30–45 minutes to develop a caramelised surface. The extended low heat converts the dense collagen network of the shoulder into gelatin, producing meat that falls from the bone with the lightest pressure and a sauce enriched by the released gelatin.
Slow-roasted lamb shoulder is one of the most forgiving luxury dishes — the technique is difficult to execute poorly once the basic principles are followed. The risk is under-cooking (collagen not converted) or over-cooking (meat dries as proteins contract past the optimal point). Within those boundaries there is substantial latitude.
- The shoulder must be sealed first — Maillard development before the low cook. Unsealed shoulder produces adequate but not exceptional flavour - Cover tightly during the long cook — steam produced by the liquid and the meat itself accelerates collagen conversion and prevents surface drying - The internal temperature target is not the doneness indicator for this cut — time and texture are. The meat is done when a fork inserted meets no resistance [VERIFY internal temperature for reference: approximately 90–95°C] - Uncovering for the final 30–45 minutes allows the surface to caramelise and the braising liquid to reduce to a glaze - Rest for minimum 20 minutes before serving — the fibres reabsorb liquid
