What You Need to Know
The gentle heat (≈90–120 °C) allows collagen in lamb or beef to hydrolyze into gelatin over 2–4 hours, producing a glossy, gelatinous sauce. The conical lid recirculates steam, keeping volatile aromatics such as cumin, coriander, and preserved lemon from evaporating, while the clay walls provide thermal insulation that prevents rapid moisture loss.
