Lamb Tagine with Preserved Lemon and Olives

A Moroccan tagine is a braise with North African spicing. The long cook turns the lamb shoulder tender; the preserved lemon and olives added at the end provide acidity and salt that cut through the richness.

Brown the lamb pieces in olive oil in a heavy casserole or tagine over high heat. Do this in batches — do not crowd the pan. Set aside.

Soften the onions in the same pot for 10 minutes. Add the garlic, cumin, ginger, turmeric, and cinnamon; cook for one minute. Return the lamb to the pot. Add the stock and enough water to come halfway up the meat.

Cover and cook over the lowest heat, or in an oven at 150°C, for 90 minutes. Turn the lamb once during cooking.

Remove the rind of the preserved lemon (discard the flesh), cut it into thin strips, and add to the pot with the olives. Cook uncovered for a further 15 minutes to reduce the sauce slightly.

Check the seasoning — preserved lemons are salty, so add salt carefully. Scatter coriander leaves over the top. Serve with couscous or flatbread.

Method

This is a braising dish built on the North African principle of balancing fat with acid and salt. The long, gentle cook renders the lamb shoulder's collagen into gelatin, creating a silken sauce; the preserved lemon rind and olives are non-negotiable additions at the end — they cut the richness and prevent the dish tipping into one-note richness.

Heat the olive oil in a heavy casserole or tagine over high heat until it shimmers. Season the lamb generously with salt and pepper, then brown it in batches — crowding the pan drops the temperature and steams the meat instead of caramelizing it. You're after deep mahogany patches on the surface, not pale grey. This Maillard reaction develops the savoury backbone of the finished dish. Set each batch aside as it's done.

In the same pot, soften the sliced onions over medium heat for eight to ten minutes until they collapse and turn translucent. Add the garlic, cumin, ginger, turmeric, and cinnamon stick; toast for exactly one minute — the heat releases the volatile oils in the spices and kills any raw bite. Return the lamb to the pot along with the stock and enough water to come halfway up the meat. This ratio matters: too much liquid and you'll end up with thin, insipid sauce; too little and the meat dries out on its exposed surfaces.

Cover and transfer to a 150°C oven for ninety minutes. A low oven maintains a gentle, even simmer — around 85°C in the pot — far more reliable than a stovetop, where hot spots cause the bottom to catch. Turn the meat once halfway through to ensure even cooking. The lamb is done when a fork slides through the shoulder without resistance and the meat begins to separate from the bone.

Meanwhile, remove and discard the flesh of the preserved lemon, leaving the rind. Slice the rind into thin strips. When the lamb is tender, uncover the pot and add the lemon strips and olives. Simmer uncovered for fifteen minutes to reduce and concentrate the sauce — you want it to coat the meat lightly, not pool at the bottom. Taste before seasoning with salt: preserved lemons are intensely salty, and the olives add more sodium, so restraint is essential. Finish with torn coriander leaves and serve with couscous or flatbread to soak the mediterranean-cuisine sauce.
