A tajine is a Moroccan dish as well as the special pot for preparing this dish. The traditional tajine pot is formed entirely of a heavy clay which is painted and glazed. It consists of two parts; a bottom which is flat and circular with low sides, and a large cone or dome shaped cover that rests inside of the bottom during cooking. The cover is so designed to promote the return of all condensate to the bottom.
Tajines dishes are slow cooked at low temperatures, resulting in tender, falling-off-the-bone meat with aromatic vegetables and sauce. The cover has a knob-like formation at its top to facilitate removing it (source: Wikipedia).
I love this shape...
The mrouzia recipe (with lamb, plums and almonds) is the one I prefer.
